OTTAWA — The Canada Revenue Agency says it has temporarily cut off public access to its electronic services over security concerns, preventing Canadians from being able to file their taxes online.
“We have received information concerning an Internet security vulnerability named the Heartbleed Bug,” the agency said in a statement posted on its website Wednesday morning.
“As a preventative measure, the CRA has temporarily shut down public access to our online services to safeguard the integrity of the information we hold.”
The affected services include EFILE, NETFILE, My Account, My Business Account and Represent a Client.
The agency said it is working to restore safe and secure access as soon as possible.
It is a busy time of year for the tax agency, as people file returns electronically and track the progress of refunds online.
As of the end of March, the agency had received 6.7 million returns, with 84 per cent filed electronically.
CRA said consideration will be given to taxpayers who are unable to comply with their filing requirements because of the service interruption.
