Members of the CanadianArmedForces (CAF) will be deployed to Saskatchewan to help battle the province's fourth wave of COVID-19.

The CAF said Saturday that up to six critical care nursing officers will be deployed to intensive care units in the province, and that it will "provide aeromedical transport" for patient transfers within and outside Saskatchewan.

"We are expecting to support the province until November 17, but are prepared to extend if necessary," the CAF said.

On Friday, Public Safety and Emergency Preparedness Minister Bill Blair said on Twitter that the federal government approved "a request for federal assistance to support the people of Saskatchewan" and that "we will have more to say on the situation in Saskatchewan shortly."

The province submitted its formal request for federal assistance last Monday, aspokesperson for Public Safety Canada told CBC News on Saturday, adding that work is to continue over the weekend to identifywhat resources are needed.

Earlier this month, eight CAF critical care nurses began work at an Edmonton hospital after the Alberta government also requested help.

Saskatchewan reported231 new cases and five additional deaths on Saturday. Hospitalization are at 288, and77 are in intensive care.

Starting early next week,up to three intensive care unit patients a day will be transferred from Saskatchewan to hospitals in Ontario. As of Friday evening, seven have already been transferred.

The Saskatchewan Health Authority said Friday it may activate the next stage of its triage plan, as COVID-19 hospitalizations continue to overwhelm the health-care system.

Saskatchewan has already sent six ICU patients to Ontario and more transfers are expected this weekend to try to ease the burden on hospitals. But doctors say COVID-19 restrictions are needed as the health-care system gets closer to collapse.

Derek Miller, the authority's chief of emergency operations, said a committee made up of doctors and ethicists is set to prepare a formal recommendation to move to the second stage of triage.

The province has been operating under the first stage for several months, which involves cancelling surgeries to free up bed space and health-care workers to focus on COVID-19 cases. The second stage would involvedoctorsconsulting with ethicists about who does and does not get life-saving care.

"It's absolutely shocking, and there's no other way to describe the direction Saskatchewan is headed," Dr. Katharine Smart, president of the Canadian Medical Association, said from her home in Whitehorse.
