Environment Canada
Nobody else deserves the credit for this one
Canada can be cold but it is not that bad depending on where you live in Canada. Canada does have a summer. It happens for two-three months a year. I live in Canada but I never have been to any of the countries listed.
I regularly check the weather network. They always give up to date information. I check the site daily.
I think the instructions are quite useful for checking Environment Canada website.
I don't think I would go to Environment Canada to check my weather forecasts.
Barry's Response - For most people, TheWeatherNetwork is just fine. Either that or EC. Only if you're really interested would I expect you to check both and compare.
