When is race season in Canada?
Short answer: September, and it isn't close. Below is every dated race on the calendar — 908 of them — sorted every way worth sorting. These numbers are computed from the live data and change nightly, so they're current rather than a snapshot someone typed once.
Races by month
September has 370 races. April has 6. Anyone who has tried to race here in early spring knows why — it's mud, thaw, and a wind that makes you reconsider the hobby. What's stranger is that December out-races April several times over. Canadian runners will take snow over slush without hesitating.
The busiest race weekends
If your local 10K always seems to clash with three other local 10Ks, this is why. Half the season is stacked into a handful of weekends.

Which provinces race most
The one that surprises people: Quebec. A large share of Québécois races never appear on the English-language race sites at all, because organizers list them on Le-Sportif rather than the platforms the rest of the country uses. If you're an anglophone runner who has never raced in Quebec, that's probably why — the races are there, just not where you were looking. They're all on the Quebec page.

What to do with this
If you want a goal race: pick September or October and work backwards. That's where the choice is, which means better fields, better organisation and more people running your pace. The season planner builds the tune-up races around whatever you choose.
If you want a quiet race: the opposite. A May or June race has a fraction of the competition for entry spots, and small fields are friendlier for a first one.
If you're a race director: look at those top weekends before you set a date. Moving one week either side of the peak can be the difference between competing with 124 other events and competing with 40.
