Proposed Amendments to Ontario Regulation 413/05


Published on: 01/11/2013

Over much of the past decade, MTO undertook a sweeping reform of the regulations governing vehicle weights and dimensions for heavy trucks, introducing Safe Productive and Infrastructure Friendly (SPIF) vehicles and vehicle configurations in Ontario. As a way of protecting a company’s investment in these pieces of equipment, vehicles operating at the time of the various regulation changes were grandfathered up to the end of their typical operating life.

Having been enacted for several years, MTO has chosen to address a number of “housekeepingâ€Â￾ modifications to the Regulation. Of interest are changes that MTO is proposing on:

• grandfathering regulations for semi-trailers and double trailers with four or more axels built before 2006 (non-SPIF trucks). MTO is proposing to modify the existing provision to allow companies to operate trucks built before 2006 for five additional years under a special permit – 20 years for trailers and 25 years for tankers (previously 15 years and 20 years respectively).

• modifying the maximum allowable spread limit on Tandem Drive Axel trucks. MTO is proposing to increase the maximum spread from the current 1.85 metres to 1.88 metres (only affecting Designated Trucks 2,4 and 5 – SPIF Vehicles #20, 22 and 23).
