The Canada Revenue Agency says it will send electronic notifications about uncashed checks to 25,000 Canadians this month.

The federal agency says it has nearly $1.4 billion in uncashed checks in its vaults that have accumulated over the years, some dating back to 1998.

Every year, the CRA issues millions of payments in the form of benefits and refunds, but some checks remain unpaid for various reasons, including misplaced checks or address changes.

Another 25,000 Canadians will receive electronic notifications in November, followed by another 25,000 in May 2023.

The CRA launched a campaign in February 2020 to encourage Canadians to cash their checks and says it has so far returned more than $800 million to taxpayers.

The CRA says Canadians can check if they have unpaid payments by logging in or registering for an online CRA account
