Canada鈥檚 highest court won鈥檛 hear a conviction appeal from a former Ontario truck driver in the death of a woman at an Edmonton hotel.

Bradley Barton was sentenced to 12 1/2 years for manslaughter in the death of Cindy Gladue.

The 36-year-old M茅tis and Cree woman bled to death in a hotel bathtub in 2011.

As is usual, the Supreme Court of Canada did not provide reasons in dismissing the application for leave to appeal.

Barton鈥檚 lawyer Peter Sankoff says he鈥檚 disappointed by the decision.

He says his client is still waiting for a ruling on a sentencing appeal with the Alberta Court of Appeal.

A jury first found Barton not guilty of first-degree murder in 2015. The acquittal sparked rallies and calls for justice for Indigenous women across the country.

Both the Alberta Court of Appeal and the Supreme Court then ordered a new trial.

There was outrage because Gladue was repeatedly referred to as a 鈥渘ative鈥� and a 鈥減rostitute鈥� during the trial. Her vaginal tissue was presented as evidence.

Court heard Barton, from Mississauga, Ont., hired Gladue for two nights of sex and she suffered a severe wound to her vagina.

Barton testified the sex was consensual and he was shocked when he woke the next morning to find her dead in the tub.

The Crown argued Barton performed a sex act on Gladue while she was passed out that caused the wound. Prosecutors said he dumped her in the tub and left her to bleed to death.

A jury in the second trial in 2021 convicted Barton of manslaughter.

Barton鈥檚 bid for a third trial was dismissed in January, after Alberta Court of Appeal judges found 鈥渘o reviewable errors鈥� in the trial judge鈥檚 rulings. Barton鈥檚 lawyers argued the judge had erred by allowing evidence that should not have been admitted at trial.

The Crown filed the sentence appeal, calling 12 1/2 years in prison 鈥渄emonstrably unfit.鈥� It had recommended Barton be sentenced to between 18 and 20 years.
