After my experiences with MTO I certainly believe that we are a target.....since an MTO Officer told me that we are.....
Any of us that tow are over 4500kg combined weight, therefore need a anual inspection (yellow sticker), which even in e-test exempt areas (Renfrew County) requires an e-test and since now you are considered a commercial motor vehicle. You don not need a CVOR though, as the you truck falls under the "personal use pickup" exemption, which means no CVOR, log book or circle check required.
Truck and trailer need a anual inspection, exept RVs. The truck has to be licenced, sticker on your plate, for the total combined wieght, truck + trailer + load, if the trialers weight, exerted on the road (not counting hitch weight) is over 2800kg. Mine is licenced for 10,000kg btw, which is about $450 per year.
In addition to that if your trailer is over 4600kg you need a class A drivers licence to pull it.
happy towing....
