I use a 70W ballastwise ballast. Here's my thread when I built a DIY canopy for my nano tank.

Ballastwise will ship to Canada, but you have to do all the work...and by work I mean you have to arrange the shipping for Fedex or someone to pickup at their location and ship to you. They really don't want to be involved in it. I found it a headache at best, but the ballast was well priced.
