A technical glitch may have affected the online organ donor registration of up to 60,000 donors.

The “Be a Donor” website problems happened between March 23th, 2013 and September 19th, 2014.

A letter asking the affected donors to update their information will be sent.

Ontario health minister Eric Hoskins says the glitch won’t affect the security of anyone’s information, and the site is back up and fully operational.
