You would think they would want to put a Timmys in the Canada pavillion.... Ah well, bringing your own is a great idea, I wouldnt have ever thought of it!
I work at a Tim Hortons here in Nova Scotia and I know if you have one of the Tim Horton's Coffee makers you can come in and get the filters that we use it's in a pkg of probably 200 but go to your local Timmies and ask cause the ones we sell for the home coffe maker are really our Tea Filters for the Steeped tea!! Hope you understand all that!! I'm on maternity leave right now so I have no idea of the price?? Hope this helps a bit!!
