Customs Broker in Ontario

Every Ontario Gateway, Covered
Windsor, Niagara and Sarnia corridors
The Ambassador Bridge and the Gordie Howe International Bridge carry the heaviest commercial flow in North America — much of it just-in-time automotive freight where an hour of border delay ripples through a production line. We file PARS before your truck leaves the U.S. side, so the barcode scan at the booth is a formality.
The Peace Bridge, Queenston–Lewiston and Sarnia's Blue Water Bridge serve southern Ontario's manufacturing and consumer-goods traffic — same approach: entry on file pre-arrival, release confirmed while the driver is still queuing.
Pearson air cargo, rail and the cities
Air cargo at Toronto Pearson and Ontario's intermodal rail terminals and bonded warehouses round out the province's gateways. Wherever your carrier enters, the clearance sits in the same account with the same flat fees.
Importers in Toronto, Mississauga, Brampton and across the GTA get dedicated local support on our Customs Broker Toronto page; Eastern Ontario importers have our head office next door — see Customs Broker Ottawa.
Classification questions? Our HS code classification service documents the reasoning behind every code, so duty rates and CUSMA claims hold up under review.

Frequently Asked Questions
Which Ontario border crossing is fastest for commercial freight?
With pre-arrival clearance on file, the honest answer is: the one your carrier prefers. Delays at modern crossings come from missing paperwork far more often than from the booth itself — which is exactly what a broker eliminates.
Can one broker handle shipments arriving at different Ontario ports?
Yes. Brokerage is federal, and all your entries — truck at Windsor, air at Pearson, rail into Toronto — clear under one account, one contact, one invoice format.
Do small Ontario businesses really need CARM registration?
If you import commercially, yes — CARM registration is a CBSA requirement regardless of company size. The good news: registration is a one-time setup we complete for clients routinely.
