I use ING Canada. I wish we had the same interest rates as you guys down in the States but I'll make do. The nice thing about it is it's a good place to park your money and forget about it. I have it drawing out $100 a week from my chequing account right now. Since I don't really think about it, its not a big deal. Of course I have the same thing happening with my RRSPs anyhow. This account is more along the lines of saving for a new car or something later on.
Cheers
