I may be wrong but I think there is no SOMA distributor in the GTA. I did hear from a cycling buddy that a shop in Cambridge might be selling them.
I am also considering getting the SOMA Smoothie (not ES) and building it up as my rain/hack bike. I will probably get the frame and fork from BikeTiresDirect.com. I have ordered a bunch of stuff from them and they know how to ship to the GTA to avoid excessive duties... I also use the ship via USPS option to avoid brokerage fees.
