Canadian multi reg's

I'm due to start my private pilot training soon, and after I am done I would
like to take my multi and IFR. I don't plan on becoming a commercial pilot,
just a private with a multi and IFR rating (endorsments)
I was just wondering if there were any words of wisdom or any special
regulations (CANADA) that I may find myself up against before I get my heart
set on getting a multi engine rating.

I'm sure the school will let me know of all the pitfalls or the rewards but,
since they are due to make money on me by training I would like to hear from
a un-biased opinion.

thanks in advance!
