Canadian Snow Load Map

Can anyone provide me with a copy of the Canadian Snow Load map or at least steer me to a location where i can get it? I need it for a sunshade project.

Thanks,

None of the Google links had the info you want?

http://www.google.com/search?q=Canadian+Snow+Load+map

http://www.canadiangeographic.ca/Magazine/jf03/alacarte.asp

Normalized ground snow load maps are also available for most of Canada from the Atmospheric Environment Service (AES) in Downsview, Ontario. ...

Google (or your favorite search engine) is always the first place to look! I just hi-lited your Canadian Snow Load Map and drug it into Google and hit Enter. Just click on the first link above to see all those results.

Welcome to CR4, it's a fun place to be most of the time!

You don't say where in Canada your project is located. If it were in Alberta, you should get a copy of the Alberta Building Code. This provides ground snow load in many localities within the province. It also provides design factors for roofs, taking into account drifting snow, etc. For other Canadian provinces, I believe similar provincial codes apply.

We also have a National Building Code which, purportedly show snow loads for all of Canada, but I don't have a copy of the latest edition, so I am not sure how comprehensive their list is.

"Commentary G Snow Loads" in "NBC 2005 Structural Commentaries" states that ground snow loads for selected locations are presented in NBC Table C-2, Design Data for Selected Locations in Canada in Appendix C of Division B.

Perhaps you could narrow the search down a bit by telling us where your project is located.

Then I would recommend that you order the National Building Code 2005 complete with User's Guide - NBC 2005 Structural Commentaries (Part 4 of Division B). You can order these from the National Research Council of Canada. Make sure to tell them you want it in English or you may get the French edition.

If you are looking for the actual snowfall amounts in certain regions in Canada, then try the Environment Canada website.

If you are looking for technical specifications for the dead and live snow loads on roof structures, you will have to visit your local city/town hall and get access to your provinces' Building Codes. You should find a table with design criteria of roofs for the expected snow loads in your area.
