Northern Ontario is a wonderful paradise of blueberries. Every time I visit, I seek out a patch. Locals have their secret blueberry patches, and will not reveal the location under any circumstance. I have visited the Shield Country enough times that I now have a secret patch too! Wild blueberries are quite small, but really tasty.
According to my search, bunch berries are also edible, but not as sweet. Rather than snacking on them, I just love how the red berries brighten up the forest floor.
