Questions

Ontario heavy haul questions

Do you haul heavy loads into Ontario?

Yes. We are based at 7660 W Third St in Dayton, OH 45417, and we haul oversize and overweight loads across the USA and Canada, with bonded and non bonded shipments across the border. Our permitting team pulls the MTO permit for the Ontario leg.

Do I need a municipal permit as well?

Often. MTO permits cover the King's highways only, so roads run by a city or region need that municipality's permit or its consent.

What do you need for the border crossing?

The weight, dimensions, commodity and customs details. The carrier sends eManifest data to CBSA at least 1 hour before arrival.

How heavy a load can you haul?

Our superload service handles loads up to 300,000 lbs, with permits, routing and escorts by our own team.
