You are unlikely to have to meet the rules unless you have an accident or run into a check stop they are rare but you do live in Ontario so this is for your information got the info from the MTO (just what we need more rules)

> Braking rules for towing in *Ontario include a 50% rule; it the trailer is over 50% of the
weight of the towing vehicle you need trailer
brakes regardless of trailer size *(legal limitation)
Your finished and loaded trailer maybe well under the 50% rule still you may want to consider
brakes; as you can see others have done the upgrade to brakes
