There is also blind skiing, my wife and brother-in-law have done it for years. I am not sure what programs they have at Whistler but if you have time perhaps check in to it before you go. You might have to spend time re-learning your skiing skills as a blind person but it certainly possible to continue skiing. There are blind skiing clubs in most provinces that can probably help with advice regarding equipment, guides and training. The $1 site has a page on skiing but unfortunately it is just a dead link. Perhaps call them and they can point you in the right direction.

Tubing is also loads of fun!

Most big resorts here in the US have adaptive programs that you can participate in. I assume where you're resort will be the same.
If the slopes aren't you're thing many also have cross country skiing areas you can try out as well.
I snowboard all the time and I know lots of blind folks that ski as well. I'd be shocked if they didn't offer it there

Tubing?
