  1. Hi. I'm not sure if you read this page anymore but I thought i would mention it. The weather records website has been down since sometime in mid March. Is it going to come back at some point? That was the only place where you could see a comprehensive book of records. Even the record on environment Canada are outdated and I don't know where else to find them

    1. Hi Matthew,

      I'm afraid the website is no longer available for the time being due to my dealings with Weatherlogics (http://www.weatherlogics.com/). I apologize for the inconvenience. Perhaps the website, or a different version of it, will return in the future.
