Catherine O'Hara passed away due to a pulmonary embolism, a condition resulting from a blood clot migrating to the lungs. The coroner's office in Los Angeles released this information on Monday, confirming that she had been struggling with underlying rectal cancer. The official report a week earlier had only indicated that O'Hara was found in serious respiratory distress at her home in California and was later taken to the hospital, where she succumbed to the condition.

O'Hara, a two-time Emmy Award winner for her performances in 'Schitt's Creek' and 'SCTV Network 90,' died at the end of January. Notable for her work in television and film, she was a prominent figure on Hollywood red carpets and starred in beloved films such as 'Beetlejuice' and 'Home Alone.' In recent years, her performances have solidified her status as a beloved actress, and she remained an admired figure in the entertainment industry.

Last year, the American-Canadian actress featured in one of the current favorite series, further demonstrating her talent and versatility. The announcement of her cause of death not only highlights the personal tragedy but also marks the loss of a significant figure in the acting realm, whose contributions have left an indelible mark on television and film history.
