Tip: Zones are estimates. Local microclimates, wind exposure and elevation can affect your actual planting conditions. When in doubt, ask a nearby nursery!
"Canada's official plant hardiness zones are based on data from 1981 to 2010. But local conditions are changing — many areas may be a little warmer now, especially near cities or lakes."

Understanding Plant Hardiness Zones: Canada vs. U.S.

Plant hardiness zones help gardeners choose plants that can survive the winter in their area. Both Canada and the U.S. use numbered zones (like Zone 3, Zone 6, etc.), but they aren't always exactly the same. The U.S. system is based only on the lowest winter temperatures. In Canada, our zones also consider other factors like wind, snow cover, and how long the growing season is. That means a Zone 6 in Canada may still be colder and shorter than a Zone 6 in the U.S. If you're looking at a U.S. seed packet or planting guide, it's safest to choose plants rated for a slightly warmer zone than your own—just to be sure they'll survive our Canadian conditions!

Hardiness Zones: Same Numbers, Different Winters

Think of plant zones like snow boots: size 6 in the U.S. might keep your toes cozy in a light frost, but here in Canada, size 6 better come with wool socks and a shovel. Both countries use numbered zones to tell us how cold it gets, but the Canadian system takes more into account—like wind, snow cover, and how long our garden season actually lasts. That means a U.S. Zone 6 might feel like a mild fall, while Canadian Zone 6 is still brushing snow off the daffodils. So when you're picking plants from a U.S. catalogue, play it safe and choose ones made for slightly warmer zones—they'll thank you when our northern chill rolls in.
