Since I'm the OP, I wanted to provide closure on this.
We crossed into Canada a couple of days ago from the UP of Michigan. I never had to leave my seat in the coach. The CBP agent asked a lot of questions about weapons... nothing about food... asked for passports and coach registration... but never even mentioned proof of insurance.
Re: the weapons... I had a hunting knife and bear spray which I had stowed in the belly and told him they were there but that I had no firearms. He seemed fine with all of that.
Thanks all for your insights.
