INFOOTTAWA — The Ontario and federal governments are preparing to unveil a joint COVID-19 rapid testing program at the province’s biggest airport as early as next week, as both sides seek to deflect blame for a growing number of travel-related cases entering Canada. A spokesperson for Ontario Premier Doug Ford said a new pilot program to test international travellers entering Canada through Toronto Pearson International Airport would be unveiled “in the early new year.” The plan is likely to test roughly 315,000 travellers for COVID-19 over a three-month period, but the arrangement has not yet been finalized, the person said.
