Need advise on winterizing pond plants.

Hardy plants can generally be left in the pond. Tropicals have to come
indoors, or be composted. If you can lower hardy plants below the maximum
depth of ice, they generally have a better chance, but some plants (irises,
rushes, watercress) survive freezing. We'd give better advice if we knew
which plants you have.

I live just west of oronto, Canada.

You either have an extra T or you're missing one :-)
