Does Quebec require a route survey?

Yes. Seasonal axle weight limits apply roughly March through May, cutting posted limits by about 20%. Overweight permits on posted roads are limited or unavailable during the window, so schedule heavy deliveries around it. Spring thaw rules by state →
Does a Quebec permit cover Ontario?
No. Every state issues its own permit, and a move crossing into Ontario, New Brunswick, or Newfoundland and Labrador needs a separate permit there with that state's escort and travel rules. FreightDeck prices every state on the route in one quote.
