The rise of the Omicron COVID-19 variant has some Canadians searching for ways to ensure their families haven't contracted the virus.

Rapid antigen tests (RATs) offer on-the-spot COVID-19 test results in less than 20 minutes and have become a hot topic. They can also be self-administered at home.

While they are available for free in some spots, not every province or territory in Canada has made them widely available. Some Canadians are being asked to pay upwards of $40 to get tested at a pharmacy.

The price and limited access to RATs is creating inequality among Canadians, advocates say.

ACCESS TO RAPID ANTIGEN TESTS IN PROVINCES ACROSS CANADA

Please note RATs are primarily meant for those who do not display any COVID-19 symptoms and are not considered definitive tests by a number of Canadian health authorities. If you develop any symptoms or test positive on a rapid test, it's recommended you self-isolate immediately and book a PCR test to confirm infection.

BRITISH COLUMBIA

Free testing through the provincial health system is currently unavailable for people who need to get tested for work or travel. However, some private clinics may offer testing for a fee. Long-term care facilities may be able to acquire tests. Businesses who wish to establish workplace screening programs can apply for access to tests. The Canadian Red Cross is also providing free rapid antigen tests to eligible non-profits, charities and Indigenous community organizations in B.C.

ALBERTA

Starting Dec. 17, Albertans can get a free RAT kit for at-home use on a first-come, first-served basis while supplies last at select pharmacies and clinics every 14 days. Employers can also apply to implement a testing program at their organization. There's also a voluntary program providing testing kits for kindergarten to Grade 6 students and staff at participating schools.

The province has made a supply of at-home, rapid self-testing kits available to the general public.

YUKON

During a COVID-19 briefing on Dec. 15, Yukon's acting Chief Medical Officer of Health Dr. Catherine Elliott said the territory is looking at how to best utilize rapid antigen testing and possibly broadening its use in the coming weeks and months. Dr. Elliott indicated such testing was currently being performed in congregate living settings, including at mines.

NORTHWEST TERRITORIES

Businesses and organizations can apply for access to rapid antigen tests with priority given to those that are involved with vulnerable populations, high-risk settings, essential services and sectors that support economic and social activities. A voluntary pilot program has also begun at select schools where, every week, randomly selected children from classrooms between junior kindergarten and Grade 6 receive at-home testing kits. More schools may be added as the project continues.
