Opti2 is available in Canada. In Alberta, Husqvarna dealers carry it. It is available in pouches, for 5 litres or 10 litres, and the usual measured bottles. I find it most convenient to use the small pouch. That way, my fuel is never stale. I might add, that Opti2 has a stabilizer in it, and quite compatible with ethanol blended gasoline. Check out Opti2 on the web for more information and a toll free number to find your closest dealer.(just enter Opti2 in the browser bar) You might find that Bosch or NGK plugs are superior to Champion.
