Canadian undergrad - disadvantage?

Hey, I've been going through this sub-forum, and I've noticed a majority of the people applying to the main B schools (H/S/etc) are from ivy or top 10 finance schools in the US.

How do Canadian schools work when it comes to such rankings? I purposely chose to study in Canada due to the cheaper education cost (~10k tuition for 1 year), but will this negate my chances to a top B school in the US (for MBA)?

Thanks.
