Sorry, I'm in Minnesota (which is the Canada of the states), but have no idea of sources for actual Canada. I got mine from the us amazon.com. I think it was around $40 iirc.
I've been using the pan daily since I posted the original review and I love it even more now. Still no warping, but if I do heat it too rapidly on my terrible electric glass top range, it does temporarily warp just enough to spin on the glass a bit. Once the temperature equalizes, it flattens back out. This would be imperceptible on a real (gas) range.
I've also noticed that the silicon sleeve has loosened up a bit from gripping it and taking it on and off (i take it off when i put the pan under the broiler and then put it back on the very hot handle when it comes out of the broiler). Not really a problem at this point, and I think a new one is like $5, but I thought I'd mention it as it's the only real wear item on the pan.
