ABSTRACT
This chapter provides a very brief introduction to how they were deployed in Canada's Coronavirus disease (COVID-19) pandemic. The high number of outbreaks in Nursing Homes and Seniors Care residences accounted for many of the cases found even in more sparsely populated provinces like Nova Scotia. Federal authorities are also required to provide 2-way communication with all provinces and territories when coordinating the influx of returning citizens and international travellers who are exiting or entering the country at the more than 140 land border crossings, 14 international airports, and over 550 port facilities that play a strategic role in Canada's goods and services supply chain. Communication strategies leveraged the power of a captive audience and the fact that 93% of Canadian adults are reached by television each week. Different countries have adopted different technical approaches and sometimes conflicting guiding philosophies to digital contact tracing.
