TORONTO (Reuters) - Canada Revenue Agency (CRA) has suspended some of its online services, including tax filing options, as a precautionary measure due to a security threat, though it assured users that no data has been lost.
"Upon becoming aware of an internet vulnerability ... we took down our online services, including electronic filing, and are taking steps to ensure that all information and systems remain safe," said a notice posted on the CRA website.
CRA said took the step after it became aware of an internet vulnerability affecting some computer servers used by websites worldwide on March 10.
"At this time, we are not aware that any personal information has been affected; however, we continue to assess and remedy the situation," the notice added.
The services will remain suspended until CRA determines that there is no longer a security vulnerability, a CRA spokesman told Reuters in an emailed statement.
Canadians have up to May 1 to file their income tax returns and benefits, which makes this period busy with online users.
CRA couldn't immediately comment on the seriousness of the threat or whether this was the first time its services had been taken off line due to security concerns.
