I don't remember seeing a stainless in any of the shops here in Vancouver. Probably best to go to your favorite SIG dealer and ask them to check with the Canadian distributor for availability and price. There are probably not a lot of these around - especially in a particular calibre like 9mm. You might have to wait for the next production run of 9mm stainless at the factory. I also think it will be tough to get one at that price. New blue 226's are fairly close to that price.
The stainless is probably a good gun for what you are aasking about in your other thread. The SIG catalog I have says it is, "Perfect for USPSA and IPSC competition" and "...a favorite among USPSA Production division shooters including Roger Sherman..."
