I've been trying to find a reliable and easy to see growing zone map for Canada and I finally found one. It's interactive and even has a place at the bottom of the page to search for specific locations. Perhaps I'm the only person who needs this but here is the link just in case. http://wms1.agr.gc.ca/cgi-bin/mapplant2000?mode=browse&layer=zones&layer=cities Up until now I was working under the assumption that we were 4a but now I see we are 5a. That opens up a whole new list of possibilities for our garden. Yea!
