That is a good site! Those 2100ft peaks refer to Elevation, if you notice their prominence (aka Vertical) it's much less. A few around 900-1300 ft but most much much smaller yet.
I'm sure there would be some decent shredding to be had though. 1000ft vert is enough for some good turns, and on a good year the snow in Northern Ontario can be fairly deep and always cold.
Maybe you should go check a few out...
