Anywhere to buy silica beads in BULK from within Canada/Canadian manufacturer?

I'm trying to find a Canadian supplier or manufacturer of silica beads, to buy in bulk. By bulk I mean 2kg - 10kg quantities, so consumer use but not casual use.

If nobody in Canada both makes AND sells to consumers, then I don't mind if the beads are made overseas, just that they're sold from a Canadian supplier and ship from within Canada

I used to buy from Dry N Dry, but they're US based, and at the moment it'll probably be damn expensive getting it shipping in (not to mention the customs I paid the first time).

Thank you
