A shroud of smoke from hundreds of wildfires across Canada has swathed North America, even extending offshore — with a Bermudian in Toronto describing smoky, eerily red-tinged skies.

Glenn Simons, a ten-year resident, photographed the deep orange moon on Wednesday morning, when it was difficult to breathe and “the news reported that the air quality in Toronto was the worst in the world”.

Mr Simons, who runs a family hair salon with his wife, said they lost some business this week when customers found the air too harsh.

Compounding the misery were sweltering conditions brought on by the “heat dome” trapping hot air as well as smoke.

Mr Simons said the humidity had been “like a bowl of soup”, even for someone raised in the Cobbs Hill area of Bermuda.

He added: “Two days ago, when they said it would get over 100, I said, ‘I lived in Bermuda; it can’t be that bad.’ It was actually that bad.”
