One-time top-up to the Canada Housing Benefit
An excerpt from Canada Revenue Agency:
The one-time top-up to the Canada Housing Benefit aims to help low-income renters with the cost of renting. You may be eligible for a tax-free one-time payment of $500 if your income and the amount that you pay on rent qualify.
The Canada Revenue Agency (CRA) administers this one-time payment. To apply for this new federal one-time payment, you do not need to receive other housing benefits such as the Canada Housing Benefit, which is co-funded and delivered by the provinces and territories.
