CRA duped in $40M bogus tax refund case. Why did it take a big bank to notice?

In 2023, a Canadian taxpayer logged into his Canada Revenue Agency account, falsely amended previous tax returns and wrongly claimed he was owed more than $40 million in refunds. Without verifying any of the newly filed tax slips, the Canada Revenue Agency authorized the payments and began making the initial instalments, according to sources.
