Buy Canadian

Kinnickinnick Foods was originally Edmonton-vased, and has recently been sold to English Bay foods out of BC.

There's a lot of good smaller-brand bread brands. As mentioned in another comment. Though because they're smaller they have a smaller reach so it some what depends on what part of the country you're in. So what province are you in?

Also I was looking this morning for some gluten free oats/flour brands and came up empty handed. My house heavily relies on Bob's Red Mill

I would say your health comes first. Buy what you can Canadian, and then if you are forced to buy American, only buy what you absolutely have to. Survival is not failure.

What foods are you buying? Maybe someone can suggest an alternative?

Fody is a Canadian company (not sure what percentage of their products are made in Canada or not though). Their lineup is targeted at people with IBS, but that includes being GF.

Am U. S. citizen. I don't have an answer, just want to wish my Canadian neighbors the best. FWIW, if you have an aldi or lidl nearby they probably have some gluten free options. The Aldi I shop at does and both companies are German based. Not Canadian, but also not U. S.
