Flower:

Flowers are in a densely packed spike-like raceme 1 to 2½ inches long at the top of the stem. Individual flowers are about 3/8 inch across with 4 white petals that drop off soon after blooming, and 4 thick creamy tipped stamens that project out like the points of a star. One plant has a single cluster, though not all plants flower.
Leaves and stem:

Sterile plants have 1 leaf; fertile plants have 2 or occasionally 3 leaves of unequal size, with heart-shaped bases and pointed tips. The largest leaf is up to 3 inches long and 2 inches wide. There are feint stripes and parallel veins along the length of the leaf. Leaves are toothless and hairless. The main stem zig-zags between the alternately attached leaves.
Fruit:

Fruit is a green berry about ¼ inch in diameter, mottled with dull pale red that ripens to dark red in late summer.
Notes:
Canada Mayflower is a common woodland spring wildflower, typically found growing in colonies of various sizes. Formerly in the Liliaceae (Lily) family, all Maianthemum species have been reassigned to Ruscaceae (Butcher's Broom).

Below the Falls at the mouth of the Creek

Our house lot was part of a tree farm - the flowers are in a small colony underneath a group of scotch pine

I have these growing all over in my native vegetative lot. Quite nice little flowers and can definitely replace the over used Lily-of-the Valley.

Along the road to the International Wolf Center.

Surprised to spot some of these in Eagan MN (Dakota County). Usually I see them further north.

I have a small patch of these growing amid sugar maple seedlings, red baneberry, and near a blue cohosh in a vegetative area under mature sugar maples.

These are growing in the pine forests near the Scenic Drive/Highway 61. They are growing near bunchberry plants.

I noticed these blooming for the first time today on our farm in Mower County.

Along the edge of the woods.

We have had these growing on our lot for a number of years.

I have quite a few showing up on my property after removing invasives.

Is the best way to distinguish these from European Lily-of-the-Valley simply the size of the leaves? I've looked at a few keys and ID guides for each species and that is the only major difference I'm really noticing. Thanks!

Jaron, leaves of the European species are indeed distinctly longer (to 8 inches) and proportionately narrower, tapering at the base, and non-flowering plants have 2 leaves; leaves of the native are usually less than half as long, more heart-shaped at the base and non-flowering shoots have a single leaf. When flowering they are easy to distinguish from the flower shape and arrangement.

We have them in many groups of single leaves. That made them hard to ID - no flower color to look up! My friend's son ID'd them from an app. We also saw them (single leaves) at Afton SP last Saturday. Are they poisonous to dogs?

They grow in the woods in yards along Ideal Street. I have a small patch of Canada Mayflowers growing in the shade under the Arbor Vitae along the East side of my house. There's also a very large patch of them growing throughout a small stand of red pines that were probably planted 80 or 100 years ago when this "Highland Gardens" area of Duluth was commercially growing raspberries. Those Red Pines are at the North end of the Helmer I. Carlson Recreational Field which was constructed on Basswood Ave in 1990.
