Small moving business owner, need info on heavy vehicle regulations

I have a small household moving business in Montreal. I'm currently using an 18' cube truck for local moves in the Montreal area. It's time for a new truck and I'm looking at buying an f-150 ecoboost and a 20' enclosed car hauler. With a new truck I also want to do more long distance moves to Ontario. And I don't really know anything about the regulations that are going to apply to me.

Quebec and Ontario seem to have different rules over what qualifies as a heavy vehicle. When I called the Quebec transport ministry they told me that a pickup truck less than 4500kg and a trailer less than 4500 kg don't have to go for inspection. And I don't have to register as owner of a heavy vehicle or keep log books.

In Ontario it's different. When I called and spoke with an Ontario enforcement officer, he told me that if my truck, trailer and cargo combined are over 4500 kilograms, then I have to stop at the scales, have the vehicles inspected, have a CVOR and log books.

I already have what Quebec calls a NIR, which I think is the same as a CVOR. I had to register when I bought my cube truck. Quebec says I don't need the NIR if I'm pulling a 9900 pound trailer. But I can probably get one if it's needed in Ontario.

So if I get the truck and trailer inspected, then have Quebec update my NIR file to include the new truck and trailer combination, and fill out a log book and do a pre-trip inspection before I do any trips to Ontario. What else am I missing? I've never had to stop and scale because I don't go out of town very often. If I'm going to Ontario with an 8000-9000 pound trailer and I have to stop at the scales what happens?

What about log books? if I have to keep a log book, what qualifies as a legal sleeping berth? My plan was if I have to do long trips, I could put a topper on the bed of the truck and sleep there. Or in the trailer. Does this count as legal sleeping berth? I read about guys having trouble with sleeping in the back of their crewcabs and getting tickets. Last thing I need is to be 1000 miles from home and get in trouble for a law I don't know about.

Hope someone here can help me out.
