Hello and welcome to the forums!
Taking lessons when you start out is probably the best thing you can do. I took 3 consecutive days of lessons and at the end of it, I was able to go on a blue (well, an easy blue :P ) and not die. But of course, I hadn't been on any sort of plank on the snow before. You will probably do that by the end of your 1st day.
I'm not familiar with any places in Canada, but one of your fellow countrymen should show up eventually and give you some pointers
