The Canada Revenue Agency has locked an unknown number of taxpayers out of its online platform, telling users their email addresses have been removed from their accounts with little explanation. Dozens of users took to social media on Tuesday and Wednesday to report encountering the same "error 021" on their accounts. Several said they spent hours waiting on CRA's helpline to get their accounts unlocked, but either received little information or no response at all. Told CRA locked my account for an unknown reason. When a reporter dialled a CRA helpline on Tuesday night, he was told to call back later "due to high demand."
