any good summer marathons in northern Canada with cool weather?

Southern hemisphere, bro. Look to New Zealand or Argentina or something.

Edmonton in late August. Prize money, flat fast course, but could be warm.

Toronto in a couple of weeks.

Vancouver Marathon - early May.

Ottawa and Calgary marathons- late May.

Vancouver is hilly and slow.

Calgary is very hilly and very slow. It used to be a flat out and back, but no more.

Ottawa can get very humid and warm, but is the best of these three.

All three of these are in Southern Canada.

You can't get much closer to the southern border of Canada. A couple of weeks is still spring.

Northern Canada is Like Fort Mac or NWT wrote:

Calgary changed their course for this year to be more like the old course and more flat

Sweet. I re-read the OP's post. In his message he does say anywhere in Canada. I take "northern Canada" to be like Yellowknife.

Edmonton and Calgary both good options.

All of Canada is in the far north and it's always winter there.

This was a joke based on typical American knowledge.

Seattle is north of Toronto.

But don't tell Americans

Here's the best choices. It depends how soon OP wants to race and where he lives now.

-Calgary (flat, fast, unlikely to be warm, but 3500 feet elevation)

-Edmonton (flat fast, but forest fire smoke risk, warm morning risk, lower elevation than Calgary)

-Ottawa (high chance of Boston-like muggy conditions, but sea level)

-Vancouver (slow hilly course, but sea level, best crowd support late in the race?)

Bay of Fundy marathon on June 23rd and Marathon by the Sea on August 11. Both are in New Brunswick along the Bay of Fundy which keeps temps surprisingly cool in summer, although they are unfortunately both hilly courses.

If you can wait until September 8 Marathon de Rimouski on the Gaspe Peninsula in Quebec would be a good bet. I've been up there in late August and it was frigid thanks to the nearby St. Lawrence. Also looks like a very flat and fast course with few turns. It's a haul to get up there but an awesome area to check out if you can get some time off after the race, especially Gaspésie National Park.

Also worth mentioning, marathons in Canada are an incredible bargain. Prices for Marathon by the Sea and Marathon de Rimouski range from about $40US for early registration to $60US for day-of(!) registration.

Forest fire smoke in Edmonton is rarely a factor. The course is flat and fast. Even though the race is in August, the morning temperatures are typically quite reasonable and the humidity is almost never high enough to be a factor. I say go for it.

A little more context might help: the 2018 Marathon by the Sea winning time was 2:48 and 10th place was 3:13. Rimouski was won in 2:16 but 10th was 2:54. I love the Maritimes and the St. Lawrence, but you could be in for a lonely run if you chose one of these races. Go for the fun and the sight seeing around either race but they're maybe not the best options if you're looking for a chance to PR.

The 2:16 guy didn't have a problem running alone.

Rimouski has some prize money, a cheap entry fee, a sliding scale of comped entry and hotel for sub 2:40/3:05 runners, a flat course, cool weather, and it doesn't benefit any charities. Sounds like a racer's race to me.

Not Canada but grandmas in Duluth mn is your best option
