Here's what we know: The Canada Revenue Agency (aka CRA, aka the folks to whom we pay taxes, aka The Tax Man) took down a large chunk of its online services on Friday afternoon, and they remained offline until Sunday night. The CRA's main website at cra-arc.gc.ca featured the following message during the outage:
Upon becoming aware of an internet vulnerability that affects some computer servers used by websites worldwide, we took down our online services, including electronic filing, and are taking steps to ensure that all information and systems remain safe.
At this time, we are not aware that any personal information has been affected; however, we continue to assess and remedy the situation.
You can still complete your tax forms, but will have to wait before filing.
