Federal government ends shipments of COVID-19 rapid tests as they are set to expire

The federal government has stopped shipping rapid COVID-19 antigen tests to provinces as millions are set to expire within the year, and experts say the once-essential tool has lost its importance in the pandemic.

There are 90 million rapid tests in the federal inventory, Health Canada said in an email. About 80,000 of those are set to expire within six months and 6.5 million within the year. The rest expire within two years.

“Canada has robust inventories and is well prepared for COVID response,” Anne Genier, with Health Canada, said in an email.

Ottawa has ordered more than 811 million rapid tests since the beginning of the pandemic with a price tag of about $5 billion. About 680 million of those went to provinces and territories.

As the fourth wave of the pandemic gripped the country near the end of 2021, every region was trying to get as many of the tests as possible. Hospitals were overwhelmed in many provinces and the rapid antigen tests became a critical part of the response.

Mahesh Nagarajan, a professor at the University of British Columbia’s Sauder School of Business, said it’s a different situation two years later.

“I don’t think we should be buying any more of them right now,” Nagarajan, whose focus area is on supply chains, said in a recent interview.

Nagarajan said Canada now has several qualified and dependable suppliers for the tests. The government has established standing offers with the companies for the supply and delivery on an as-needed basis

Health Canada said the decision to end shipments at the end of January was made in collaboration with provinces and territories, as the regions have enough supply.

On top of the federal stockpile, provincial health authorities said theyhave millions of tests.

British Columbia has 28 million tests, with more than four million to expire within six months.

Quebec has 63 million tests, Alberta has 47.5 million, Saskatchewan has 6.4 million, Manitoba has 11 million, Nova Scotia has about 8 million and Newfoundland has about 2.5 million.

Nearly every region said they have so far not destroyed or repurposed their rapid antigen tests, because Health Canada extended the expiration date for many brands. They did not explain an expected cost or strategy if the tests expire before being used.

The time frame left for the tests differs depending on the brand,but Health Canada has approved 19 extensions of shelf life ranging from six months to two years.

The chemical components in the tests degrade over time, Nagarajan said, so he has concerns.

Having large stockpiles of rapid antigen tests may not be useful, especially if the virus shifts and becomes less detectable on the devices, said Dr. Anna Banerji, an infectious disease specialist at Dalla Lana School of Public Health and Temerty Faculty of Medicine at the University of Toronto.

“Even at the best of times there are limitations on the testing,” she said.

What is important is the ability to quickly produce or procure them, she added.
