Hi, here is what I found.
Here is a link to the rules and regulation from Transport Canada.
Most inspectors will use a drone that weight less than 2kg and all inspectors carry liability insurance. That’s pretty much all you need.

Those are the rules established in November 2014.

If you use a bigger drone and need the Special Flight Operations Certificate, you can take the course here: http://www.ccuvs.com/ for $500.
Hope it helps.
