Trucking Regulations (Oversized Load Permit)

Under the Ontario Highway Traffic Act (HTA), the City of North Bay has a number of by-laws which regulate the movement of trucks through the City.

Truck Routes

To address the needs of the trucking industry and to limit the detrimental effects of trucking on specific roadways, the City of North Bay has established a network of roads designated for use by heavy vehicles. The following is an excerpt from the City of North Bay By-law:

Traffic By-law 2014-38

3.13 Truck Routes

  1. The highways or portions of highways described in Schedule 8 are designated as truck routes.
  2. Where official signs are posted, no person shall operate or park a heavy vehicle on any highway in the City other than on the highways designated as truck routes in Schedule 8.
  3. Notwithstanding subsection (2), a heavy vehicle may be driven to make a direct delivery to or collection from a bona fide destination in the City, provided that the operator of the heavy vehicle proceeds by the most direct route between the nearest truck route and the place of delivery or pick up in the City, and on the completion of the conduct of business, the heavy vehicle is returned by the most direct route to the nearest truck route.

3.14 Load Limits on Bridges 

  1. The bridges at the locations set out in Schedule 9 are designated as bridges for which load limits are prescribed.
  2. Where official signs are posted, no person shall drive or move a vehicle or combination of vehicles over any bridge described in Schedule 9 where the gross weight of the vehicle or combination of vehicles exceeds the gross weight limits listed in Schedule 9.

Reduced Load Period (Half-Loading)

To reduce the effects heavy vehicles have on roadways during the spring thaw, the City of North Bay has declared a period of reduced loading on certain roads for the period from March 1 to May 15 inclusive. The actual duration of the restriction may vary depending on the road conditions. During the reduced load period, the maximum allowable weight shall not exceed five tonnes per axle. All roads covered by half loading are posted with the appropriate regulatory signs. Refer to the Reduced Load By-Law 2004-45 Schedule A for a map of roads designated for reduced loads.

Oversize Load Permit

The City of North Bay issues permits to allow the movement of oversized / overweight vehicles and loads which exceed the limits set out in the Highway Traffic Act (HTA) on roads under its jurisdiction.
