Just got back from 4 days in Thunder Bay Ontario. Some things I learned.
Seatbelts are mandatory everywhere.
Local Police, Fire and Medical are top notch.
Canadian citizens are great, almost vomitously polite. It felt like we were in bizarro world as people went out of their way to assist us. It felt "normal" to cross back into the US and experience our first road rage driver.
Canadians drive too slow. The speed limit on freeways was 90km/h (56mph) but everyone stuck to around 40mph.
Never cross into Canada with three other men dressed in suits and long coats, unless you're there for business. We were questioned by Customs/Immigration for 30min because of our dress. One young guard said we were "dressed suspiciously for leisurely travel". Perhaps it didn't help that our resident smartmouth Dan said in his best Russian accent: "We vont to make good impression een your country". Thankfully they recognized our attempts at humor and finally let us pass.
When crossing the border, it helps to have reservations at a hotel as opposed to saying "we're just going to look for one". It also helps to carry more than a driver's license; preferably also a birth certificate, passport, or some other form of ID.
When returning to the US, it makes it easier if you have receipts from the Hotel where you've stayed.
If I were a smuggler, which I'm not, it would have been too easy to smuggle something, even firearms, into both countries. Canadian Customs searched the inside of our car and trunk only. They did not look under the car or under the hood. US Customs did likewise. There were also no drug/bomb sniffing dogs present. It may have been due to the particular people working those days, but we were surprised.
All in all, Canada is a great place to get away for a few days.
