There is quite a few of us canadian's here - MOST are from the GTA. Best bet for an airfilter would be Wemoto, unless Nuak has a couple around. I got mine in a big box full of parts from a Honda dealership in Australia however.
I was also planning on trying to get all of us out for a ride & bbq at my place. I live around the Barrie area and its the perfect starting point for a great ride into the muskoka areas. Amazing roads up here, like Southwood Rd: http://www.youtube.com/watch?v=pkAeJGkEq4E&feature=related
Its not the worlds best rd, but it is one of Ontario's better roads. Besides, its only 20 minutes from my house.
