Edit: Probably should have googled first, apparently there's a product called "Lin Speed Oil". Seems you can't order it from the manufacturer, and doesn't look like anyone in Canada carries it either. Brownells does have Lin Speed Oil, no idea if they'll ship it to Canada though.
Rona carries both raw and boiled linseed oil, Recochem (sp?) is the brand as far as I remember. Might have another brand as well.
Any home improvement/hardware store with a paint section worth walking through should have some form of linseed oil. I don't think Lee Valley has LO though, but they've got a decent selection of other wood finishing products.
