Outdoot October Wedding

Hi there! We are planning an outdoor wedding for the Canadian Thanksgiving weekend (Oct 10th) in the Cornwall region. Would it be possible to know the predicted wether around that time, also considering the dew at night. I was also interested in knowing the peak colour changing time for our region. Any help would be greatly appreciated!


Winter will you be as cold as it was a few years ago at -30-40?
I hope you will have good news for summer 2020.Summer 2019 has not been famous heat level a summer like 2018 would be welcome for the south shore of montreal.

So to sum up, if I understand

So to sum up, if I understand correctly, it shall feel like winter from early to mid, and late season, yes?
