Most common wear items land same day from GTA suppliers. Anything on backorder gets a firm date before you approve it.

What we source

The parts that keep units moving.

We price the choice rather than making it for you. A truck with two seasons left does not need the same part as one you plan to run for six.

Brake and air system partsLinings, drums, chambers, valves, dryers and hardware kits from lines we trust.
Aftertreatment componentsDPFs, DEF pumps and injectors, NOx and pressure sensors — OEM or reman, priced both ways.
Engine componentsInjectors, turbos, water pumps, EGR coolers and gasket sets.
Suspension and steeringAir bags, shocks, bushings, kingpins, U-bolts and hangers.
Driveline partsClutch kits, U-joints, carrier bearings, seals and differential components.
Electrical and lightingBatteries, alternators, starters, harnesses, lamps and connectors.
Filters and fluidsCorrect-spec oil, coolant and DEF, plus filter sets for scheduled PM.
Trailer partsLanding gear, suspension, brake and lighting components for trailer repairs.
How it runs

You see the options before we order.

01

Identify

Part confirmed against the VIN and the unit, not guessed from a catalogue photo.

02

Price both ways

OEM and quality aftermarket quoted side by side with availability on each.

03

You choose

Nothing gets ordered until you pick. Backorders get a firm date first.

04

Fit and warranty

Installed here, with the part warranty and the invoice in your records.

Book it

Need a part priced?

Send the unit, the VIN if you have it, and what you need. We come back with both options and real availability rather than a guess.

Truck down waiting on a part? (905) 677-7663
Do you sell parts over the counter?+

Our focus is parts fitted here, so the warranty and the records stay in one place. Call and ask — for straightforward items we can often help.

Is aftermarket worth it?+

On plenty of items, yes. On aftertreatment and safety-critical parts we usually recommend OEM or reman, and we will tell you which is which.

What if a part is on backorder?+

You get a firm date before approving anything, plus the alternative if one exists. What you will not get is a truck sitting in our yard with no answer.
