Hi everyone ~
This plant is not related to the dogwoods, that would be the Bunchberry, or
Cornus canadensis. This woodland flower is starting to flower right now, and it is called the Canada Mayflower. In French, it's 'le Maiantheme du Canada' related to its scientific name,
Maianthemum canadense.
Here's a link to its description and more photos:
