Considering the age of your laptop, finding a fully functional battery from any site is going to be a crap shoot. I know several sites that have your needed battery but whether they can provide a good battery is not a given. And returning that battery for a replacement is troublesome.
I could google for a Canada site, but that is what you should be doing. I can not recommend any battery source that would give you a fully functional battery for such an older model laptop. I normally source part numbers from the EU ASUS eStore. It doesn't even list your model.
Good Luck
