We don't eat pemmican anymore but it was like a super protein/high energy mix for long travels. Sounds gross but it used to be a thing. We have roots and stuff, yes, that is in the wild edibles, berries , wild veg classification I descried. It's just different all over Canada, it's a lot of land and not all the same! and there is too many to list. Many plants and their roots are edible. You can make a similar tasting drink o coffee with toasted dandelion roots.

Acorns are for squirrels, we eat the spruce tips...feels less scratchy on the tongue XD

You will survive just fine!
