If you haven't filed your income tax return yet, you'll get an extra five days to do so due to a shutdown of a federal government website.
The Canada Revenue Agency and some other government departments have put their sites back up after being down for five days because of the so-called Heartbleed bug.
It attacks software commonly used on the Internet to provide security and privacy and the federal government took down affected sites as a precaution.
The tax agency says its site is safe, but it's pushing back the traditional April 30th deadline to file a return without facing interest or penalties.
Revenue Minister Kerry-Lynne Findlay says the new deadline is May 5th.
The Heartbleed bug is affecting many global IT systems in both private and public sector organizations and has the potential to expose private data.
