PRINCE.EDWARD.ISLAND (CBC) - More people are falling sick with flu symptoms in locations across Canada, increasing demands on health-care services.

Health officials in British Columbia confirmed three more deaths from swine flu on Wednesday. All victims had pre-existing medical conditions.

None of the patients were children. A fourth patient, a schoolgirl from the Yukon, has also died in the Vancouver area.

In B.C., 162 people have been admitted to hospital with flu in the past week, and family doctors in the province are seeing eight times more patients than usual for this time of year showing flu-like illness.

In Newfoundland and Labrador, health authorities are reporting a second H1N1-related death. Both deaths happened in central Newfoundland.

As of Tuesday, the Public Health Agency of Canada reported 101 deaths from H1N1, six more than reported on Oct. 29.

Meanwhile in Sudbury, Ont., 47 people have been hospitalized with flu, including nine people who are on ventilators. The city has a population of 158,000.

Sudbury has cancelled elective surgeries, which some hospitals from Vancouver to Montreal are also doing.

Hospitalizations in Ontario have increased "measurably" over the last month, Ontario's chief medical officer of health, Dr. Arlene King, said Wednesday.

"Hospitals are coping well with this surge. We do not have any reports of hospitals being overwhelmed, however, some primary care settings and emergency departments are very busy and that's why special flu assessment centres have been set up across the province."

Flu assessment clinics have opened in cities such as Windsor, N.S., and Edmonton. People with flu symptoms can go the clinics to get checked out to help ease the pressure on family doctors and emergency rooms.

In most cases, patients can be sent home for treatment. Some are also being admitted to hospital.
