When news first broke, Reuters’ initial report on O’Hara’s death said the “Schitt’s Creek” and “Home Alone” star had died after a brief illness. The fuller medical picture surfaced later in AP’s report on her death certificate, which said a pulmonary embolism was listed as the immediate cause, with rectal cancer as the underlying condition, and that an oncologist had been treating her since March 2025.
Catherine O’Hara final days: What the reports say
The clearest personal account so far came from her brother, Michael P. O’Hara. In People’s account of his recent podcast remarks, he said O’Hara “wasn’t talking much in the end” and “didn’t really want to talk on the phone,” adding a personal detail to the official timeline.
Taken together, the reports help explain why the illness was widely viewed as private. Public confirmation at the time was limited, and the medical details surfaced only after official records became available.
A career still in motion before the end
The later revelations landed harder because O’Hara had remained publicly active. In a January 2025 Entertainment Weekly interview about “The Last of Us” Season 2, she was still teasing a darkly comic role opposite Pedro Pascal. That late-career momentum had been building for years, including the high point captured in AP’s coverage of the 2020 Emmy Awards sweep for “Schitt’s Creek”, when her performance as Moira Rose helped anchor one of television’s most memorable victories.
That long arc — from a career-defining awards run to fresh TV work less than a year before her death — helps explain why the later disclosures felt so jarring to fans. On screen, O’Hara looked as sharp and busy as ever; off screen, the hardest part of her life appears to have remained largely her own.
Legacy beyond the final headlines
O’Hara’s body of work stretched from “SCTV” and “Beetlejuice” to “Home Alone,” Christopher Guest’s mockumentaries and “Schitt’s Creek.” The new reporting does not change that legacy, but it does add a quieter final chapter — one marked by privacy, family and a struggle that, by most public accounts, stayed out of view until after she was gone.
