when summer end in canada
Rating Newest Oldest. Best Answer: I'm not sure where Frank and Ben live, but in Canada we have four seasons...Spring, Summer, Autumn, and Winter. They seem to think you switch from Summer with beautiful sunny days right into snow. Summer officially starts on our about June 21st and ends on or about September 21st. As you mentioned, some people say the 21st, some say the 22nd, I even heard the 23rd this year. I believe that it changes from year to year, possibly due to those leap year days that pop in every so often in February.
