It's roughly 12 hours and 35 minutes driving from Toronto to Cleveland and back. Driver has a 14 hour day, of which he can drive 11 hours in the U.S. and he picks up an extra 2 hours driving when he crosses back into Canada. Goes off duty as soon as he hits the dock back in Toronto. That would definitely work for the first round of the week, assuming all the stars line up at shipping, receiving, and customs. If the driver uses PC (personal conveyance) miles back to Fort Erie, then he's golden for the rest of the week. Do an 8/2 split on Friday, reset over the weekend, and he's good for another week.
Again, I'm not saying it's right. I'm just saying if I were going to cook the books, that would be how I would do it. Although, if the driver lives in the Fort Erie area, that's not cooking the books at all and is "grey area" legal for the PC miles, especially if he is running empty to Cleveland.
