Catherine O’Hara died of blood clot in lungs, says L.A. death certificate

The Canadian comedian Catherine O’Hara’s death certificate says she died from a blood clot in the lungs, with cancer listed as the underlying cause.

A Los Angeles County death certificate that was issued Monday lists a pulmonary embolism as the immediate cause of the actress’s death, and says rectal cancer was the long-term cause.

The Toronto-born actress known for Emmy-winning performance in “Schitt’s Creek” and for her role as Macaulay Culkin’s mother in two “Home Alone” movies, died on Jan., 30, at the age of 71.

The oncologist who signed off on the certificate indicated that he had been treating the actress since March of last year.
