Routing through Canada

Check your permit book, if you have Ontario permits and Canadian insurance you should be legal, but there's many other considerations, also you need to meet logging standards for Canada which include keeping 14 days of logs instead of 8, having a rest period of at least 24 hours in the past 7 days, and to reset 70 you need 36 instead of 34 hours.
also if you went into Canada you need to file an electronic manifest to CBSA and get it cleared before showing up at the border, don't have any guns, pepper spray, switchblades etc when you show up, oh and remember, freedom isn't free, have ten dollars for Homeland Security when you reenter America. I'm not sure how cars are regulated as cargo. you would be covered under cabotage rules so long as you only transite

Just drive the 100 miles.

 

That would be an insane amount of extra paperwork plus dealing with border patrol on both ends. I would run the extra 100 miles even if I was legal in Canada.

I'm with you on the CD miles though, it nearly got me once on a Michigan to MA load. The miles just seemed a bit short, glad I checked on my phone. Broker wouldn't up the price either, I passed on it.

 

I believe it's $13.05 now. Several times I've crossed and they were too busy to collect it.

 

Sometimes they refuse to give change.

It is easier to just drive the 100 miles if it is a one off load. If you were doing it every day I'd say you would be better off to do it.
