Thinking about it....
Maybe you have to start grouping Eastern Ontario, with southern Ontario,
as our weather seems to match better with theirs, rather than with southern Quebec.

Predictions, Wrong again?

Well once again, I think they got it wrong....'Winter will be colder than normal, on average, with much above-normal precipitation and snowfall.'
It has been much warmer and drier than normal, here in eastern Canada, till the end of January.
I don't know if Feb./March '21, will cool off enough to make it a 'colder than normal winter'.
Sometimes March is the snowiest month....

No complaints here

Michael, considering that our snow removal in Montréal is terrible under the best circumstances we should consider the lack of huge snowfalls a blessing this year


This didnt age well... worst canadian winter ever up till date. Not one major snowstorm in Quebec yet. I think Quebec winter's has changed for good.


outdoor wedding october not outdoot

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?
