The table below distills the confirmed details of her life and death.

What condition did Catherine O’Hara have?

Medical records released after her death shed light on two distinct health issues: a rare congenital heart defect she lived with for decades and the terminal illness that ultimately took her life. The Healthline (health news outlet) reported that her death certificate listed pulmonary embolism as the immediate cause of death, with rectal cancer as the underlying cause.

What rare disease did Catherine O’Hara have?

• In 2020, O’Hara publicly discussed having dextrocardia with situs inversus, a rare congenital condition in which the heart is positioned on the right side of the chest instead of the left (Fox News (news network)).
• Fox News noted that dextrocardia usually does not cause problems on its own, and experts said it is unknown whether this condition contributed to her death.

What was the cause of her death?

• The Los Angeles County Medical Examiner’s Office determined on February 9, 2026, that the cause of death was a pulmonary embolism — a sudden blockage in a lung artery caused by a blood clot traveling to the lungs (ABC News (broadcast news network)).
• Rectal cancer was listed as the underlying cause, according to Healthline.

The implication: While her rare cardiac condition generated public curiosity, the official record points to cancer as the root cause. No evidence has surfaced linking dextrocardia to her death.

What this means: The medical record is clear — the pulmonary embolism was the immediate cause, and rectal cancer the underlying cause. No link to her lifelong cardiac anomaly has been established.

Is Catherine O’Hara of Irish descent?

Yes, across multiple sources. O’Hara was born in Toronto, Canada, to Irish Catholic parents: Mary (née O’Leary) and James O’Hara. Her ancestry is predominantly Irish (Wikipedia (open encyclopedia)). In interviews she often spoke warmly of her Irish roots and Catholic upbringing.

Are Maureen O’Hara and Catherine O’Hara related?

Despite sharing the same last name and both being celebrated actresses, Maureen O’Hara (1920–2015) and Catherine O’Hara were not related. The similarity is purely coincidental (Wikipedia (open encyclopedia)). Maureen was an Irish-born Hollywood star known for films like The Quiet Man.

Is Catherine O’Hara pro LGBTQ?

O’Hara was a vocal advocate for LGBTQ+ rights throughout her career. Her role as Moira Rose on Schitt’s Creek — a series widely celebrated for its positive LGBTQ+ representation — reflected her inclusive values (Wikipedia (open encyclopedia)). She publicly supported marriage equality and often credited the show’s creator, Dan Levy, for championing authentic queer stories.

What this means: Her advocacy was a deliberate career-long choice, not a late-career gesture.

How old was Catherine O’Hara?

She was born on March 4, 1954, and died on January 30, 2026, making her 71 years old at the time of her death (Wikipedia (open encyclopedia)).

What was her early life like?

• Growing up in a large Irish-Catholic family in Toronto, she was the youngest of five siblings (Wikipedia (open encyclopedia)).
• She attended Burnhamthorpe Collegiate Institute and later studied at the University of Toronto before dropping out to pursue comedy performance.

What were her career milestones?

• Began her career on SCTV (1976–1980), where she co-created the iconic character Lola Heatherton (IMDb (film database)).
• Played Delia Deetz in Beetlejuice (1988) and Kate McCallister in Home Alone (1990).
• Won multiple Emmy Awards for her role as Moira Rose on Schitt’s Creek (2015–2020).
• Appointed to the Order of Canada in 2020, one of the country’s highest civilian honors (Government of Canada (official honors registry)).

The pattern: O’Hara didn’t chase fame; she chased funny. Her trajectory from Canadian sketch comedy to global film stardom and then to an acclaimed television swan song reflects an artist who never compromised her instincts. Each role built on the last, culminating in a career that felt both inevitable and surprising.
