So out of curiosity where you moving from?
A full list of restricted and prohibited can be found here;
http://www.rcmp-grc.gc.ca/cfp-pcaf/fs-fd/rp-eng.htm
In quick summary if it looks like a AR-15, M-16, or is classified a variant it's restricted. Under 18.5" in barrel length for center fire semi auto, or able to reduce in size by folding etc to less than 26", is restricted. Full auto's, and some that look like scary uber rifles (like Dragunov) are prohibited. Read the list for more depth.
So if it's not on that list you should (theoretically) be able to get it in Canada. There's always exceptions on what the US State department and RCMP decide on what to let through of course, the SCAR is a current good example of a rifle that may/may not be available in Canadian borders.
