Just a quick note in case you missed it. CRA is allowing your employees working from home to write off some of the expenses without having to do T-2200’s

Employees working from home with “modest expenses” will be able to claim up to $400 in the 2020 tax year without the need to track detailed expenses. And employers will, generally, no longer be required to confirm the status of employees by completing a T2200 form for each remote worker.
