Lesser and cackling Canada's will definitely mix in with the snows and snows will come in to Canada's that are in a field already. I don't think greater Canada's prefer to mix in with the snows but inevitably do with the influx of them all around the state. If I were targeting a field that had a lot of big honkers using it I might forego the snow spread. But early in the season like this with new birds in I might just throw a massive spread at them and see what happens. Good luck, hope it works out!
Take a look at what the live birds are doing and match that.
Thank you for all your input. I will report back on how it went.
