As someone who has been across the border a couple of times,the Canadian customs guys are usually ok to deal with.It would help if you had a list of all major items on board, but not necssary.Just make sure that you have no firearms,and are not bringing anything to leave or sell in Canada.
There are more that a couple of nice tracks,Mosport and Shannonville in Ontario,and St Jovite/Mont Tremblant in Quebec, plus Atlantic Motorsport Park in Nova Scotia[our home play ground]
Your US $ goes a little farther here too,and the Canadian organisers will take your SCCA license.
Give us a try, we'll guarantee a good time.
