Chill hours in Canada
Ten-season averages for 15 locations in Canada, from NASA POWER hourly temperatures. 2 of them have a full page with the season-by-season table and the fruit trees and berries that suit them.
Where fruit grows in Canada
Canadian tree fruit is concentrated in two narrow, lake-moderated corridors: the Okanagan Valley in British Columbia and the Niagara Peninsula in Ontario. Both bank chill early and hold it, so the constraint on variety choice is usually winter cold hardiness and spring frost rather than a shortage of chill.
Across these locations the ten-season average runs from 277 chill hours at Penticton, British Columbia, to 1984 at Vancouver, British Columbia. 45°F Hours and Utah are counted over 1 November – 28 February.
