Payroll deductions and automatic bank withdrawals are automatic ways to save. Both can be set up via your online account. In both cases, you determine the amount you want to contribute and can adjust that amount at any time.
Payroll deductions let you make contributions to your RRSP+ with the Fonds with each paycheque, so you get to enjoy your tax savings immediately. Your employer needs to offer this savings option for you to benefit from it.
Automatic bank withdrawals also allow you to make ongoing contributions to your RRSP+ with the Fonds. However, you don't receive any tax savings at source. Contributions are withdrawn from your bank account and you receive your tax savings when you file your annual tax return. What's more, automatic withdrawals can be set up online in minutes.
