We’re happy to share that shipments to the United States have now resumed!

However, due to recent changes in U.S. import policy, a tariff now applies to all shipments entering the U.S. To cover this added cost, an $18 CAD (approximately $12.95 USD) fee will be applied per item shipped to the U.S. This will appear as a shipping fee during checkout.

Pricing & Currency Notes

All prices listed on our website are in Canadian dollars (CAD).
If you’re ordering from the United States, your credit card will automatically handle the conversion to U.S. dollars at the current daily exchange rate.

In most cases, you’ll see your final charge appear in USD on your statement — typically around 30% less than the displayed Canadian price, depending on the exchange rate at the time of purchase.
