Proudly Canadian Owned and Operated

We are a proud Canadian-owned and operated retailer offering a range of Canadian-made products, and fully support efforts towards local manufacturing and sourcing. We are happy to offer these high-quality products to both fellow Canadians and the wider world.


Most of our products come from providers that have a Canadian warehouse. But some are imported. During this period, certain products are not readily available due to high import tariffs. With changes happening so rapidly, it's impossible to keep adjusting every product on the website. We will contact you if your order isn't available and issue a full refund. Don't hesitate to call us in advance for a stock check!


We encourage you to choose products from Canadian warehouses, such as
Kayak-ity-yak, Clearwater Design, Mustang Survival, Scubapro, and Shearwater.
