Calgary had no ambulances available an average of 420 times per month to start 2022

Data from Alberta Health Services indicates Calgary's ambulance performance and response times continue to decline as red alerts more than doubled in the first six months of this year compared with the same period in 2021.

Red alerts refer to those instances in which no ambulances were available in the system to respond to emergency calls.

The data was obtained by the Opposition NDP through a freedom of information request and shared with CBC News.

In the first six months of 2022, there were 2,522 red alerts recorded, an average of 420 each month. The highest month recorded was in April, when 618 incidents were recorded. There were 1,233 red alerts recorded in the first half of 2021, and 2,358 recorded in the entire year — meaning this year's numbers have already surpassed that mark.

The average of 420 more than doubles what was recorded in the first six months of 2021, when an average of 205 red alerts per month were recorded. The average for the first six months of 2020 was 145 per month, with a total of 3,324 recorded that year.

Mike Parker, the president of the Health Sciences Association of Alberta, said the data supported what the union had been saying for months — that the province's health-care system is "decimated."

"Time and time again, AHS will say that there's always an ambulance available. And the data does not support that conversation," Parker said. 

"It supports what we've been saying from the beginning. We don't have enough people, we don't have enough paramedics on the streets to take care of Albertans' needs."

AHS has said that higher-than-normal volumes of seriously ill patients, the continued impacts of the COVID-19 pandemic and increased staff absences relating to illnesses have contributed to the "significant pressure" on the system.

But others have been raising the alarm about the continued red alerts for years. In late 2020, critics said the system was "teetering on the razor's edge."

"We can't continue to blame it on staff shortages due to COVID or those sorts of factors," said Lorian Hardcastle, who teaches health law and policy at the University of Calgary.

"This is a persistent problem. And the government needs to do something about it sooner or later. We don't want to get to a point where we have several catastrophic incidents where people die waiting for ambulance."

In early July, AHS announced that nine new ambulances were now on the streets of Calgary and Edmonton. The goal was to relieve some of the pressure.

But Parker called that news a "non-announcement," adding that the problem was the availability of paramedics to complete the work, not the vehicles they use to get there.
