Canada actually has a lot of garter snakes... eastern garter, butlers, red-sided, plains, wandering, puget sound, maritime, eastern ribbon, northwestern, valley, etc.

Has nothing to with the hobby, also there are 13 subspecies of sirtalis... most are available and many are common in the hobby. Such as red-sided, blue stripe, california red-sided, oregon red spotted, puget sound, eastern and San Francisco(EU).
