Too far North for RES?

Is this due to short growing season? Or is there an amount of ice that will winter kill them? The parts of ontario that I visit are straight East of my house in Michigan, perhaps Bocomo knows Jay123 and knows that the particular pond in question is much farther north in ontario?

I would guess their winters are similar to lower western Michigan winters except we get more Lk Michigan lake effect snow. I'm wondering if RES would work in my area so I'm curious to learn about how to over-winter them.

I don't plan to aerate (pond only 9-10' deep in deepest, 1/3-1/2 acre depending on ground water with gradual taper to shore) as we hope to ice skate on it.

I did wonder if you could run the aerator in short bursts, maybe on a timer 2 hours on, 2 hours off just in the 12 overnight hours to get a little oxygen under the ice but yet not thin the ice to make it unsafe for skating? Does anyone have experience with the idea of intermittent aeration under a ice pack?
