If you have extra cash to invest and have a low-risk tolerance, the safest option to consider, though you won’t realize an actual return, is to put the minimum balances in your chequing accounts to avoid paying monthly banking fees.
Compared to the minimum required balance on a typical chequing account, this provides a guaranteed return of approximately 5% or more, depending on the account, since you save the monthly banking fees each month.
Another low-risk option that will provide small returns includes putting your money in a high-interest savings account (HISA).
