Local Source for Fluval 404 parts?

[Dekker500]

Anyone know of a local store (hopefully in south or west Ottawa) that has parts for a Fluval 404 in stock on their shelves? Specifically cover gasket, impeller cover, and possibly impeller shaft?

I tried Big Al's in Kanata but no luck.

If not, I'll just order the parts in. I usually don't mind ordering, but that make/model has 4 different versions and I'd hate to receive the wrong part.

Thanks!
