grow in Lake Ontario?

This year our boat is docked at the marina on Toronto Island. We're at
the end of the dock and next to our boat is a big empty space that's
not in the way of anyone. Just wondering if I can grow a hardy
waterlily in there. The problems I see are water temperature, and
oxygen level of Lake Ontario.

Another option might be the yellow American lotus, Nelumbo lutea,
since it has naturalized in Canada.

I would find out the laws about planting in a public waterway.
