Toronto-Dominion Bank is joining Bank of Nova Scotia in telling many employees to continue working from home for the rest of the year — and maybe longer -- to fight the Covid-19 pandemic.

“For most colleagues currently working from home, we expect that this will remain the reality until the end of the calendar year, and possibly into 2021,” Kenn Lalonde, Toronto-Dominion’s executive vice president of human resources, said Wednesday in a memo to the bank’s Canadian and U.S. employees. “In cases where colleagues are required to return to the office, we will make every effort to provide four weeks advance notice.”

Those employees who are already going into work, such as branch staff, will have to wear face masks at all Toronto-Dominion locations and when visiting customers, clients and vendors, Lalonde said. Visitors will be encouraged to wear masks as well, even in places where doing so isn’t mandatory. The bank, Canada’s second-largest, also created a mobile app for health and exposure screening, with a daily self-assessment required for employees to enter a workplace.

“With jurisdictions moving at different speeds to reopen local economies, we believe that this is the right approach at this time,” Lalonde said. “It helps us to provide the necessary safe environment for those colleagues who need to be at TD locations to perform their work, while reducing the strain on health, transit and other local infrastructure in the community.”

While Scotiabank is planning to keep most of its headquarters employees working from home for the rest of the year, Toronto-Dominion’s directives are wider-reaching. Toronto-Dominion has about 89,600 employees, mostly in Canada and the U.S., where it has significant retail operations along the East Coast.
