A 15-minute COVID-19 test kit was recently approved in the U.S. — why is Canada so far behind?

Imagine if there was a test for COVID-19 that could be done in 15 minutes, costs only $5 and didn't require a laboratory. Such a test was recently approved for use in the States - and it's raising hopes that soon airlines will be able test passengers, theatres could test guests, and restaurants and retailers could regularly test employees, even customers.
