Hey I posted this for someone else this link has pretty good info on what you can bring in
http://www.cbsa-asfc.gc.ca/publications/pub/rc4151-eng.html and I remember there were other links I posted on the same post that were helpful. If this one doesn't clear all the question you might want to look for for the old post.
Let me know if you find it if not i'll get the links for you
