Oversize Load Permits

Dufferin County follows the maximum weight and dimensional limits for loads as set by the Ministry of Transportation for Ontario (MTO):

  • Length - combination of vehicle and load not to exceed 23 metres
  • Width - combination of vehicle and load not to exceed 2.6 metres
  • Height - combination of vehicle and load not to exceed 4.15 metres

Any vehicle and load combination on a Dufferin County road in excess of these amounts requires an Oversize Load Permit.

Please note that this permit covers Dufferin County Roads only. For travel on town and township roads please contact the town or township directly.

The County of Dufferin offers three types of Oversize Load Permits:

  • Temporary Permit - $50/per. Valid for one transport for a specified time period
  • Annual Permit - $250/per. Valid for the calendar year. The MTO has increased its options for Annual Oversize Load Permits by offering permit enhancements for specific types of loads. Dufferin County now offers similar options on the Annual Oversize Permit application.
  • Special Annual Permit - $250/per. The MTO refers to these permits as Project Permits. Commonly used when 5 or more oversized loads are being moved within the calendar year, which do not conform to any of the Enhanced Annual Permit options. Additional reporting is required. Valid for the calendar year.

Allow a minimum of 2 business days for processing.
