Going to Canada? Not an issue!
I am a Canadian who lives in Canada and commutes to the States to work. (Where I sell sleds by the way) Given the events of late the waits can be a little longer if you go at peak times. Try to avoid returning on a Sunday evening. Canada Customs requires 3 pieces of ID now, at least one needs to be a government issued photo id. Be certain to have your sled registrations handy as well as your trailer reg.(although they rarely aske for them, they do require you to prove you own them or they could keep 'em.) All you require is a trail permit (which is about $30 cheaper if you buy before Dec1.) If you plan to go at least twice it pays to get the season permit which is when converted to USD is about $100. So to sum it up. Canada wants you to continue to come enjoy our awesome trails, simply have your id, and registations and you will have NO issues. The Canadian trails simply CANNOT be beat!
A side note, no handguns are allowed in Canada. Make sure to exchange your money at the border. Once you get inland many vendors offer poor exchange rates on US funds.
