Yes, if you purchase from PlayOsmo.com, there may be duties and taxes due at delivery that are not included in the purchase price (notably in Canada). If applicable, we display a notification to that effect in the PlayOsmo.com shopping cart.
Canada
While we are unable to estimate duties and taxes to Canada, know that they are consistent with what each province levies against the MSRP (list price) of the Osmo products (not the sale price). Here is a Canadian website that might be useful for estimating purposes (select 'Toys' as the category).
Indigo, Amazon.ca, and Best Buy Canada stores also carry Osmo products. You may want to check availability of the product you're looking there to avoid duties and taxes and to receive the order sooner. Osmo's shipping point to Canada is in the U.S. (San Diego) and the shipping method is ground.
