I'm from Canada too (North Bay, ON) and have never seen either of those products anywhere.
I use Oxyclean Baby (I buy mine in a trigger pump) or Independant Grocers/No frills/anywhere that cells President's Choice products, has a product called "President's Choice, Colour-Safe, Active oxygen Bleach. 100% Chlorine-Free. Environment friendly Products."
It has a green label, with the word Green on it in large writting. It looks like a bleach bottle.
Hope that helps.
