Kelley Lee and Anne-Marie Nicol: Why Canada doesn’t know how many COVID-19 cases are linked to travel

Opinion: If we’re going to make effective policy decisions, we need far better data. Often-cited numbers likely under-represent travel-related cases and overlook infection risks along an entire journey.

Prime Minister Justin Trudeau recently announced new travel restrictions and COVID-19 testing and quarantine rules in an effort to limit the spread of coronavirus.

Arguments against the adoption of stronger travel-related measures in Canada during the COVID-19 pandemic often point to data suggesting relatively few cases are linked to travellers. The main source of this data is the Public Health Agency of Canada (PHAC), which regularly reports on sites of potential exposure to the virus in Canada, including domestic and international flights.
