24/7 Emergency Roadside
Breakdowns don't keep office hours. One call to dispatch sends a fully equipped service unit to your driver's exact location.
Quantum Fleet Repairs
Mobile truck & trailer repair serving the whole of Ontario and all highway corridors — we bring a full garage to your yard, your dock, or the roadside, 24/7. Across the whole GTA, our ETA is 45–60 minutes.
Who We Are
We come to you. Our mobile service units bring a full garage to your yard — anywhere in Ontario — and perform major repairs and ongoing maintenance onsite, so your fleet skips the tow, the shop queue, and the lost day.
Every unit carries dealer-level diagnostics, air and brake tooling, tire equipment, electrical gear and common fleet parts, so most jobs are finished on the first visit — not diagnosed today and repaired next week. You get a clear ETA when you call, an upfront estimate before work starts, and photos and a detailed work record when it's done.



Our Services
From a no-start at 3 a.m. to scheduled maintenance across your whole fleet, our mobile units carry the diagnostics, parts and tooling to finish the job onsite — for trucks and trailers, anywhere in Ontario. Every service call includes an upfront estimate, documented diagnosis, and verification before the unit goes back into service.
Breakdowns don't keep office hours. One call to dispatch sends a fully equipped service unit to your driver's exact location.
Dealer-level scan tools and live data analysis to pinpoint faults fast — sensors, aftertreatment, fuel, air and no-start conditions diagnosed on the spot.
Brake chambers, valves, airlines, airbags and suspension components serviced and replaced onsite to keep your units safe and inspection-ready.
Blowouts, flats and worn rubber handled roadside or at your yard — tire changes, repairs and torque checks that get the unit rolling again.
Batteries, starters, alternators, wiring faults and full lighting repairs — the electrical gremlins that sideline units, traced and fixed first visit.
Doors, floors, landing gear, lights, brakes and ABS — full trailer service at your yard or in the field, so your equipment is never the bottleneck.
Scheduled inspections, fluid service and wear-item replacement organized by unit and work order — small fixes on schedule instead of big ones on the highway.
Onsite welding and metal repair for frames, brackets, decks and body damage — structural fixes done where the unit sits.
Pre-trip and periodic inspection support that catches defects before the scale house does — documented, organized and fleet-ready.
Lift gates that won't lift or lower, run slow or uneven, or have electrical or hydraulic faults — cylinders, hoses and safety checks included. On Trucks · On Trailers
Hydraulic cylinders, hoses, fittings, leaks, pumps and valves on trucks and trailers — traced, repaired and pressure-checked onsite.
Running-gear service for fuel tankers, chemical tankers and gas trailers — brakes, suspension, air, tires, lights, landing gear, inspections and PM, with extra precautions matched to the load: no flammables, anti-static clothing and full PPE kits. See Special Loads →
Full tire replacement as well as roadside tire change — a blown or damaged tire swapped where the unit sits, torqued and checked so the driver can roll safely.
Dead battery? We boost start the unit onsite and test the battery and charging system, so a simple no-start doesn't turn into a tow — and doesn't repeat tomorrow.
Locked out of the cab or need key help? Our locksmith service gets your driver back in without damage and back on schedule — one call, day or night.

Reach us any time at 437-238-1300 with the unit number, location and what's happening. You get a straight ETA on that call — 45–60 minutes across the whole GTA — and an honest timeframe anywhere else in Ontario.
Before work starts you get an upfront estimate — call-out, labour and likely parts explained clearly. No work beyond what you approved, and no surprises added later. If we find something else, we call you first.
A mobile service truck heads to your driver — yard, dock, customer site or highway shoulder — stocked for the faults fleets actually have. Diagnostics, repair and verification are done where the unit sits, with before-and-after photos and work documented against the unit and work order / PO number.
The Quantum Standard
A breakdown shouldn't cost you a tow, a bay wait and a day of revenue. Quantum brings certified-grade diagnostics and repair capability to wherever your equipment already is.
Why Quantum
A breakdown is already costing you money. The repair company shouldn't add uncertainty on top of it. Here's exactly what you get with Quantum — speed you can plan around, pricing you see before we start, and paperwork your office doesn't have to chase.
Across the whole GTA, we target 45–60 minutes from your call to a technician at the unit. You get the ETA up front, and if traffic or distance changes it, dispatch tells you — you never have to call and wonder where we are.
We fix the unit where it sits — yard, dock, customer site or highway shoulder. Skipping the tow and the bay wait is often the difference between a delayed load and a delivered one.
Dealer-level diagnostics and fully stocked mobile units mean we arrive ready for the faults fleets actually have — engines, brakes, air, tires, electrical and trailers — not just to look and leave.
Licensed technicians with WSIB coverage and liability insurance. Your safety, compliance and vendor requirements are covered before we ever touch a unit.
A real person answers at 437-238-1300 — nights, weekends and holidays. One number for every driver and every unit, anywhere in Ontario.
Work is organized by unit and work order / PO number from the first call, so dispatch, drivers and accounting are all looking at the same job — no confusion, no duplicate billing.
Our fastest-response commitment across the entire GTA. Call, get your ETA confirmed by dispatch, and a stocked service unit is on its way.
Serving the whole of Ontario and all highway corridors. Outside the GTA we give you a straight, realistic ETA on the call — and we keep you updated until we arrive.
You approve the call-out, labour and expected parts first. The price you approve is the price on the invoice, unless you approve a change.
If we find additional work, we stop and call you with photos and a price before doing it. Nothing extra is billed without your go-ahead.
Every job is documented with photos, so you can see what failed, what was replaced, and what your driver is rolling on — even if you're in another province.
Detailed invoices tied to the unit and work order / PO number, with labour, parts and work performed itemized — so your office can match and pay in seconds.

Trucks
Mobile truck repair across the whole of Ontario and all highway corridors — roadside, in your yard, or at a dock.

For The Truck Itself
A truck down is never just one problem — it's a missed pickup, a driver waiting, and a load going late. Quantum's mobile units are stocked and tooled for the faults trucks actually stop for, and every job starts with an upfront estimate and ends with before-and-after photos and a clear record by unit and work order / PO number.
Across the whole GTA, from your call to a stocked service unit at your unit. Province-wide, dispatch confirms a straight, realistic ETA on the call.
Upfront estimate before work, approval before anything extra, before-and-after photos, and an itemized invoice tied to the unit and work order / PO number.
Truck Work — In Detail
Each group below explains what the work covers and when to call for it. If you're not sure which group your problem fits, call anyway — diagnostics is how we find out, and dispatch will tell you straight what we can do onsite.
When the truck won't move, this is where it starts: get a technician to it fast, find the real fault, and fix it there.
Covers: A fully equipped mobile service unit dispatched to the truck's exact location — highway shoulder, yard, dock or customer site — day or night, with the tools and common parts to repair onsite rather than just assess.
Call when: The truck is stopped, unsafe to drive, or a load is at risk — especially outside shop hours.
Covers: Dealer-level scan tools and live-data checks to trace fault codes, warning lights, derates, intermittent faults and no-start conditions to the actual cause before parts are replaced.
Call when: A warning light, loss of power, derate, or a fault that keeps coming back — guesswork gets expensive.
Covers: Onsite boost start for dead batteries, followed by a battery and charging-system check so you know whether it was a one-off drain or a battery / alternator about to fail again.
Call when: The truck cranks slowly or not at all, was left with lights or accessories on, or sat parked and won't start.
Covers: Lockout help to get the driver back into the cab without damage, and key help to get the unit moving again, arranged through one call to dispatch.
Call when: Keys are locked in the cab, lost, or damaged and the driver is standing outside a truck that needs to move.
The systems that stop the truck and keep it level and stable. Faults here are safety faults — they don't wait for the next scheduled shop visit.
Covers: Brake chambers, slack adjusters, drums and rotors, airlines and ABS faults — inspected, adjusted and replaced onsite, then verified before the truck returns to service.
Call when: Long stopping distances, pulling to one side, brake warnings, ABS lights, or a defect found on a pre-trip inspection.
Covers: Tracing and repairing air leaks and air-system faults — compressors, air dryers, valves, tanks and airlines — so the system builds and holds pressure the way it should.
Call when: The truck loses air parked, builds pressure slowly, the low-air warning comes on, or you can hear a leak.
Covers: Airbags, levelling valves, shocks, springs and related components checked and replaced where the truck sits, restoring ride height and stability.
Call when: The truck leans, sits low on one side, rides harshly, or an airbag or levelling fault is visible or audible.
The two most common reasons a good truck stops: rubber and power.
Covers: Full tire replacement — not just a temporary fix — including fitting the replacement tire, checking the wheel and hardware, and torquing to spec before the driver rolls.
Call when: A tire is worn, damaged or failed beyond a safe repair, at the yard or on the road.
Covers: A blown or flat tire changed where the truck stopped, with the spare or a replacement fitted, torqued and checked — no waiting for a tow to a tire shop.
Call when: A blowout or flat on route, day or night, anywhere in Ontario.
Covers: Batteries, starters, alternators, wiring faults and complete lighting repair — traced with proper testing, not parts-swapping, and verified before the unit leaves.
Call when: No-crank or intermittent starting, charging problems, dead or flickering lights, or trailer-light faults traced to the truck.
The working gear on the truck, plus the scheduled care that stops breakdowns happening at all.
Covers: Lift gate diagnosis and repair: gates that won't lift or lower, run slow or uneven, drift, or stop mid-cycle — including electrical and hydraulic faults, cylinders, hoses, switches and safety checks, plus routine maintenance to keep the gate reliable.
Call when: A delivery can't be made because the gate failed, moves unevenly, leaks, or needs its regular maintenance and safety check.
Covers: Hydraulic cylinders, hoses, fittings, leaks, pumps and valves on trucks — leaks traced to source, damaged hoses and seals replaced, and the system tested under load.
Call when: Visible hydraulic fluid, slow or weak hydraulic operation, a burst hose, or a cylinder that won't hold.

Call when: A cracked bracket, broken mount, or metal damage that's keeping the truck out of service.
Covers: Preventive-maintenance inspections and scheduled maintenance by unit — wear items, fluids, brakes, tires, lights and air and suspension checks caught on schedule instead of on the highway.
Call when: A unit is due (or overdue) for its PM, or you want small defects fixed before they become roadside calls.
Grouped By Frequency
Drawn from the work that comes in day after day — the frequent jobs first, then the regular scheduled work, then the occasional faults that still stop a truck cold.

Trailers
Mobile trailer repair across the whole of Ontario and all highway corridors — brakes, suspension, air, landing gear, doors, lights, tires, lift gates, hydraulics, inspections and PM, at your yard, a dock, or the roadside. Plus dedicated support for special-load trailers: see the Special Loads page.
← Back to home
For The Trailer Itself
A trailer fault strands freight just as completely as a truck fault — and trailers often sit in yards where a shop trip means a tractor, a driver and half a day. We bring the shop to the trailer, document the work with before-and-after photos, and invoice clearly by unit and work order / PO number.
Across the whole GTA, from your call to a stocked service unit at your unit. Province-wide, dispatch confirms a straight, realistic ETA on the call.
Upfront estimate before work, approval before anything extra, before-and-after photos, and an itemized invoice tied to the unit and work order / PO number.
Trailer Work — In Detail
Grouped the way trailer faults actually happen — running gear first, then the loading gear, then tires, lights and inspections.
The running gear. If any of this is wrong, the trailer shouldn't be loaded — and most of it can be repaired right in your yard.
Covers: Brake chambers, slack adjusters, drums, valves and ABS faults inspected, adjusted and replaced onsite, then function-checked before the trailer goes back into service.
Call when: Brake defects on a pre-trip, uneven or weak braking, ABS warnings, or a trailer flagged at inspection.
Covers: Leaks and air faults traced through Glad Hands, airlines, tanks, valves and brake and suspension air circuits — repaired and pressure-tested so the trailer holds air.

Covers: Airbags, levelling valves, shocks, springs, bushings and hangers checked and replaced in the yard, restoring ride height and load stability.
Call when: The trailer leans, rides low, sways, or shows a failed airbag or worn suspension component.
The gear that has to work before a trailer can be dropped, loaded or secured.
Covers: Landing gear legs, gearboxes, cross-shafts and handles repaired or replaced, including legs that are bent, seized, stripped or mismatched in height — plus welding of mounts and brackets where needed.
Call when: A leg won't crank, drops, is bent or damaged, or a dropped trailer can't be coupled safely.
Covers: Swing and roll-up door repair: hinges, rollers, tracks, latches, locks, seals and panels — adjusted and repaired so doors open, close and seal properly and freight stays secure and dry.
Call when: A door is jammed, off its track, won't latch or seal, or was damaged at a dock.
Covers: Onsite welding for frames, brackets, landing-gear and door mounts, decks and cross-members — the metal repairs that keep a trailer working instead of waiting for a shop slot.
Call when: Cracked, bent or broken metalwork found on inspection or after dock or yard damage.
What keeps a trailer legal, visible and rolling — and what catches the rest before it fails.
Covers: Trailer tire replacement at the yard or roadside, and roadside change of a blown or flat tire — fitted, torqued and checked, including a look at the matching tire and wheel.
Call when: A trailer tire is blown, flat, worn or damaged, on route or spotted in the yard.
Covers: Full trailer lighting and electrical repair: lamps, markers, ABS and signal circuits, plugs, junction boxes and wiring faults — traced and repaired so the trailer is visible and legal.
Call when: Lights out, intermittent, or a wiring fault — especially before a trip or after a defect notice.
Covers: PM inspections, scheduled maintenance and annual inspection support for trailers — brakes, suspension, air, tires, lights, doors and landing gear checked as one visit, defects documented by unit, and repairs quoted upfront before work goes ahead.
Call when: A trailer is due for PM or its annual, a yard check is planned, or defects keep being found on the road instead of at home.
For trailers that load from the ground, the gate and its hydraulics are the job.
Covers: Lift gates that won't lift or lower, run slow or uneven, drift or stop mid-cycle — electrical and hydraulic faults, cylinders, hoses, switches, platforms and safety checks, plus routine maintenance.
Call when: A delivery or pickup is blocked by a failed or unreliable gate, or the gate is due for maintenance and a safety check.
Covers: Hydraulic cylinders, hoses, fittings, leaks, pumps and valves on trailers — leaks found and fixed at the source and the system tested in operation.
Call when: Hydraulic fluid on the ground or deck, weak or jerky operation, or a burst hose.
Trailers carrying fuel, chemicals or gas get the same running-gear work — brakes, suspension, air system, tires, lights and electrical, landing gear, inspections and PM — with extra precautions matched to the type of load the unit is carrying: no use of flammables, special anti-static clothing and full PPE kits to ensure full safety and security. We service the trailer unit and its running gear; we do not do tank-internal or tank-certification work. Its own page explains each load type in detail.

Fleets Of Every Size
Scheduled PM programs, annuals, inspections and on-site yard service for mixed fleets of trucks and trailers, across the whole of Ontario and all highway corridors. The system is the same whether you run a single unit or a large fleet: every job tracked by unit and work order / PO number, priced upfront, and documented with photos.
← Back to home
From A Single Unit To A Large Fleet
Small fleets don't get a smaller service. A single-unit operator gets the same dispatch line, the same 45–60 minute GTA ETA, the same upfront estimates and the same paperwork as a large fleet — and a large fleet gets one vendor, one number, and one consistent record across every truck and trailer.
Across the whole GTA, from your call to a stocked service unit at your unit. Province-wide, dispatch confirms a straight, realistic ETA on the call.
Upfront estimate before work, approval before anything extra, before-and-after photos, and an itemized invoice tied to the unit and work order / PO number.
Fleet Work — In Detail
Built around preventing roadside calls, passing inspections, and making your office's life easier — not just fixing what's already broken.
The core of a fleet program: the right checks, on the right units, on schedule — in your yard.
Covers: A preventive-maintenance program organized by unit: inspection intervals tracked, visits planned around your operation, and each visit covering the wear items, fluids, brakes, tires, lights, air and suspension checks a unit is due for.
Call when: You want breakdowns prevented instead of reacted to, and a maintenance rhythm your operation can plan around.
Covers: Hands-on PM inspections unit by unit, with defects found, photographed, documented and quoted upfront — so you decide what gets fixed now and what gets scheduled.
Call when: A PM visit is due, or you want a clear, honest condition report across a group of units.
Covers: The follow-through work from PM findings and regular upkeep — brakes, tires, lights, air and suspension items, landing gear and doors on trailers, lift gates and hydraulics — done in planned yard visits instead of emergency calls.
Call when: Defects are piling up between breakdowns, or several units each need a few small jobs.
Keeping every unit's paperwork and condition inspection-ready, all year.
Covers: Annual inspection support for trucks and trailers: units prepared, inspected, defects documented by unit, and the repairs needed quoted upfront and completed so the unit passes and returns to work.
Call when: Annuals are coming due across part or all of the fleet and you want them handled in your own yard.
Covers: Periodic safety and PM inspection visits that catch defects — brakes, tires, lights, air leaks, suspension, doors and landing gear — before a roadside inspection or a breakdown does.
Call when: You want an independent, documented check on fleet condition between annuals.
Covers: Repairs flowing from inspections and driver reports, grouped by unit and work order so nothing found gets lost: each defect priced, approved, repaired and photographed.
Call when: Inspection or pre-trip reports are generating defects faster than they're being closed.
One visit, many units — trucks and trailers together.
Covers: A mobile crew in your yard working through a list of units in one visit: PM, inspections, and the brakes, tires, electrical, air, suspension, door, landing gear, lift gate, hydraulic and welding work those units need.
Call when: Several units need attention and sending them out one by one would cost more in time than the work itself.
Covers: Trucks and trailers serviced under one program and one dispatch number — no separate vendors, no separate paperwork, one record per unit whether it has an engine or not.
Call when: Your fleet is a mix and you want one accountable service partner for all of it.
Covers: Owner-operators and very small fleets get the full system — scheduled PM, annuals, roadside cover, and WO/PO-documented invoicing — scaled to one unit, with nothing watered down.
Call when: You run one or a few units and want fleet-grade maintenance without fleet-grade overhead.
When a fleet unit stops anyway, the same system answers.
Covers: Every unit in the fleet covered by one number, 24/7, across Ontario — with a 45–60 minute ETA across the whole GTA and work billed cleanly against the unit and work order.
Call when: Any fleet unit, any driver, any time — one number on the cab card and in the driver's phone.
Covers: The three classic day-killers, handled as fleet services: tire replacement and roadside tire change, boost start / jump start for dead batteries with a charging check, and locksmith lockout and key help.
Call when: A driver is stopped by a tire, a dead battery, or keys locked in the cab — anywhere, at any hour.
Covers: Upfront estimates, approval before extra work, before-and-after photos on jobs, and itemized invoices tied to unit and work order / PO number — so your office reconciles in seconds and drivers are never the go-between on price.
Call when: You want maintenance spend you can audit unit by unit, without chasing paperwork after every job.

Special Loads
Running-gear service for trailers carrying special loads, across the whole of Ontario and all highway corridors. We service the trailer unit and its running gear — brakes, suspension, air, tires, lights, landing gear, inspections and PM — with extra precautions matched to the type of load the unit is carrying, so every job is done with full safety and security around units carrying, or that have carried, hazardous and special loads.
← Back to homeOur work is on the truck/trailer unit and its running gear: brakes, suspension, the air system, tires, lights and electrical, landing gear, and inspections and PM. Extra precautions are taken on every special-load job according to the type of load the unit is carrying — no flammables or spark sources are used around the unit, and our technicians wear special anti-static clothing and use full PPE kits to ensure full safety and security. We do not claim tank certification, hazmat handling, or tank-internal work. For anything tank-specific, call dispatch on 437-238-1300 to confirm scope first — if it's outside what we do, we'll tell you straight on that call.
Running-gear work we do: Trailer brakes and ABS, suspension and airbags, air leaks and the trailer air system, tire replacement and roadside tire change, lights and electrical, landing gear, and trailer inspections and PM — all done around the unit in the yard or at the roadside.
Extra safety & care: Precautions are matched to a unit carrying fuel: a careful walk-around and visual safety checks before work starts, extra attention to leaks, lights, brakes and tires, and no work begun until the area and the unit are safe to work on. No flammables, open flames or spark-producing materials are used around the unit, and technicians wear special anti-static clothing and a full PPE kit for the whole job.
Call dispatch on 437-238-1300 to confirm scope for any tank-specific work before we roll.
Running-gear work we do: The same full running-gear coverage — brakes, suspension, air system, tires, lights and electrical, landing gear, inspections and PM — scheduled as yard visits where possible, so the work is controlled and documented by unit and work order.
Extra safety & care: Precautions are matched to the type of chemical load the unit is carrying: visual safety checks first, work kept strictly to the running gear and external unit, and dispatch confirms the unit's status and scope with you before a technician is sent. No flammables are used around the unit, and technicians wear special anti-static clothing and the PPE kit suited to the load to ensure full safety and security.
Call dispatch on 437-238-1300 to confirm scope for any tank-specific work before we roll.
Running-gear work we do: Brakes and ABS, suspension, air leaks and air system, tire replacement and roadside change, lights and electrical, landing gear, and inspections and PM for gas truck trailers — in the yard or on the road.
Extra safety & care: Precautions are matched to a unit carrying gas: a careful approach and visual check before any work, strict attention to leaks, electrical and lighting condition, and tank-specific questions confirmed with dispatch on 437-238-1300 first. No flammables or spark sources are used around the unit, and technicians wear special anti-static clothing and a full PPE kit to ensure full safety and security.
Call dispatch on 437-238-1300 to confirm scope for any tank-specific work before we roll.
Safety on a special-load job is never one-size-fits-all. Before any work starts, we take extra precautions according to the type of load the unit is carrying — fuel, chemical or gas — to ensure full safety and security for the driver, the load, and everyone around the unit.
Across the whole GTA, from your call to a stocked service unit at your unit. Province-wide, dispatch confirms a straight, realistic ETA on the call.
