Pill, 27, and Baruchel, 30, met on the set of the film Goon and got engaged in December 2010. Although they were planning to wed in September 2012, the nuptials were postponed.
"Unfortunately, we're two busy people who are intrinsically lazy," Baruchel told The Times Colonist last month. "So in our free time, the last thing we want to do is book flights and organize hotel rooms for people. But it'll happen at some point."
While the date of their split is unknown, Pill did not wear her engagement ring at The Newsroom's PaleyFest panel on Sunday.
