Catherine O’Hara passed away at the age of 71 following a brief illness. Known for her “unforgettable performances,” she leaves behind a legacy defined by warmth, originality, and fearless creativity. While specific medical details were not shared publicly, the news prompted an outpouring of gratitude from fans who grew up with her characters and carried them into adulthood.

For many audiences, O’Hara will always be Kate McCallister in Home Alone, the determined mother racing across continents with humor and heart. Years later, she captivated a new generation as Moira Rose in Schitt’s Creek, transforming the eccentric character into a cultural icon. Across 80 episodes, her theatrical flair and vulnerability helped turn the series into a “global phenomenon.”

Her career extended far beyond these roles. O’Hara was a cornerstone of ensemble comedy, especially in the improvisational films of Christopher Guest, where subtle character work shone. She also returned to the world of Beetlejuice years later, proving her enduring appeal. Even late in her career, she continued to pursue new projects, focused on honest storytelling rather than trends.

Born and raised in Toronto, O’Hara grew up as one of seven children. She met her husband, production designer Bo Welch, while working on Beetlejuice, and together they raised two sons. Her final public appearance was at the Primetime Emmy Awards in September 2025. In remembering her, many choose to focus on the joy she consistently delivered—laughter that felt “effortless and deeply human.”
