Hey Psionic, I'm just down the road from you in Kitchener.
I was all worried about having enough power for my M80s leading up to the purchase. I am now finding that a 100w receiver is plenty of power for me in my 20x11x8 room. I can push these speakers up to uncomfortable levels without any noticable clipping/distortion. At one point I found an online calculator and figured I was using around 60w to get up to 90-95db, louder than I usually listen.
Spend the next 5 weeks figuring out what features you need in your receiver. Thats probably much more important than worrying about power.
