Frost dates [Montreal] & trustworthy sources

I've been questioning the frost date, in particular the last spring frost date, of May 3rd, 2009 which they give here ...

http://www.thegardenersresource.com/frostzonechartcanada.html

It says it's provided by Environment Canada.

Montreal last spring frost May 3, 2009

Montreal first fall frost October 7, 2009

Without much experience using frost dates my question is that this seems a little early. I'm used to hearing people say they plant during the long weekend in May. Even so the long weekend in May this year is a week earlier[so I understand].

Where do you usually turn to obtain your current frost dates and how accurate do you find the information? Obviously it's a great benefit when planning your seed sowing.

Thanks in advance for your experienced input/advice.

PS. the Farmer's Almanac gives the same frost dates
