My understanding was the curriculum had more classes (a year longer) and less flexibility for course selection (you can't major in CS and get a minor in history for instance). Your electives are going to be engineering classes.
In the French Canadian system you generally don't do major/minor, you study only one field. It's relatively rare to do it another way. Electives are the same that way but you have 5-6 engineering-only societal classes (economics, ethics, etc...)
