I live in Canada and have ordered stuff from the US or had relatives send stuff. It can be very expensive, but it depends on the value of what you are having shipped. I can't remember the number but I think it's something like, under $100 dollars and you don't pay anything and then after that you pay more the higher the value of whatever you having shipped. I'm sure you could look it up somewhere online though.
If you don't mine my asking, what are you planning on getting and from where? It's not very often that there's something in Canada that's not also available in the US!

Thanks Calico. I ended up calling customs and found out I wouldn't be charged anything since the value was not too high. I purchased a pair of Sevens on sale at a Canadian on-line shop called 'Ssense.'
