Searching this, I see a couple options, mainly in the 'Eco-friendly' direction. (e.g. Made of corn husks or silk, etc.)
Has anyone found/tried a Canadian made floss? Any good? I can't seem to find any at local stores, so it seems like a lot to spend to buy a single pack of floss and ship it here.
Option+ makes a flosser (pre-strung holder) which is quite competitive with Oral B and GUM in both price and quality -- Well.ca has 90 for 50 cents more than 90 Oral B, and it's cheaper when we get it at Uniprix (Quebec).
Oral B is not Canadian but it's made in Ireland, if you care about that. Still an American company so any profits on top of what the Irish workers got are going there.
