The stars of Schitt’s Creek have mourned the loss of the legendary Catherine O’Hara.

On 30 January, the Emmy and Golden Globe-winning icon’s manager confirmed her untimely passing to Variety. She was 71.

The news prompted an outpouring of grief from millions of fans and fellow performers who worked with O’Hara over her illustrious fifty-year career, including her co-stars from Schitt’s Creek.

Dan Levy said it was a “gift to have gotten to dance in the warm glow” of O’Hara’s “brilliance for all those years.” The Canadian actor co-created the Emmy-winning sitcom with his father, Eugene Levy, starring as David Rose, with Eugene as Johnny and O’Hara as the iconic matriarch, Moira Rose.

“Having spent over fifty years collaborating with my Dad, Catherine was extended family before she ever played my family,” Levy continued. “It’s hard to imagine a world without her in it. I will cherish every funny memory I was fortunate enough to make with her. My heart goes out to Bo, Matthew, Luke and every member of her big, beautiful family.”

Eugene Levy first worked with O’Hara on the Canadian sketch comedy series Second City Television (SCTV), which ran from 1976 to 1984. The pair reunited multiple times over the years, particularly in Christopher Guest’s mockumentary comedies: Waiting for Guffman (1996), Best in Show (2000), A Mighty Wind (2003) and For Your Consideration (2006).

“Words seem inadequate to express the loss I feel today,” Levy said in a statement to USA Today. “I had the honor of knowing and working with the great Catherine O’Hara for over fifty years.
