The agency says that Peel Public Health has directed the afternoon shift at the Toronto Exchange Office to self-isolate for 10 days.
The Toronto Exchange Office is located within Canada Post’s Gateway West facility near Pearson International Airport.
Canada Post says the office is where inbound international mail items arrive for review and clearance by the Canadian Border Service Agency.
The agency says it’s making contingency plans to minimize the impact on customers.
Impacted employees who were not scheduled to work Wednesday were also contacted with instructions to self-isolate.
Peel Region has also ordered the partial closures of the Canadian Tire distribution centre at 8550 Goreway Drive, Brampton and the Kintetsu World Express facility at 100 Sandalwood Parkway West, Brampton.
