Catherine O’Hara Died of Pulmonary Embolism: What We Know

When the news broke that Catherine O’Hara had passed away, many fans asked the same question: how did the beloved actress from Home Alone and Schitt’s Creek die? The answer, confirmed by her death certificate, points to a medical chain that began with rectal cancer and ended with a pulmonary embolism. Here’s what we know, what remains unclear, and how her co-stars reacted.

Cause of death: Pulmonary embolism ·
Underlying cause: Rectal cancer ·
Place of death: Home in Los Angeles ·
Date of death: January 30, 2026

Key facts about Catherine O’Hara’s death

Six facts, one pattern: the immediate cause was a blood clot, but the root was a cancer she had kept private.

The implication: the chain from rectal cancer to pulmonary embolism is a well-documented medical pathway, but O’Hara’s case was not made public until after her death.

What did Catherine O’Hara die from in real life?

Official cause: pulmonary embolism

• Immediate cause of death was a pulmonary embolism — a blood clot that traveled to the lungs (Los Angeles Times (breaking news)).
• The Moffitt Cancer Center (oncology authority) confirmed that medical examiner reports list pulmonary embolism as the immediate cause.

Underlying condition: rectal cancer

• The death certificate listed rectal cancer as the underlying long-term cause (Moffitt Cancer Center).
• Rectal cancer forms in the inner lining of the rectum, which connects the colon to the anus (Moffitt Cancer Center).
• The cancer had been kept private and was only revealed on the death certificate (Oncodaily (cancer news aggregator)).

Death certificate confirmation

• The Los Angeles County Medical Examiner released the death certificate information on February 9, 2026 (Los Angeles Times).
• The cause-of-death chain was rectal cancer leading to pulmonary embolism (Oncodaily).

The catch: While the death certificate offers official closure, it does not specify how long she had been battling rectal cancer or whether she was aware of the clot risk.

How and when did Catherine die?

Sequence of events leading to hospitalization

• O’Hara was hospitalized in serious condition in late January 2026, then discharged to her home (YouTube (news roundup)).
• The death was initially described as following a brief illness (YouTube).

Date of death

• Multiple reports state Catherine O’Hara died on January 30, 2026, at age 71 (Los Angeles Times).
• The news broke widely on February 9, 2026, when the death certificate was released (Los Angeles Times).

What this means: the family had at least a week of private grief before the official cause became public — a common but painful gap.

How did Levy react to Catherine O’Hara’s death?

Dan Levy’s statement: ‘a collective loss’

• Dan Levy, O’Hara’s co-star on Schitt’s Creek, posted a heartfelt tribute on social media, calling her death “a collective loss” (Reddit (fan aggregation)).

Other co-star tributes

• Fans and other Schitt’s Creek cast members expressed grief on social media, though no other formal statements have been published as of February 2026.

The pattern: O’Hara was deeply connected to her co-stars; the Levy tribute captures the personal weight of losing a scene partner turned close friend.

“A collective loss.”

How many children did Catherine O’Hara have?

Her family: number of children and spouse

• Catherine O’Hara had two sons with her husband, production designer Bo Welch (Wikipedia (biographical reference)).
• She married Welch in 1992, and the family lived in Los Angeles.

Why this matters: her role as a mother was a defining part of her private life, away from the cameras.

Who has passed away from Home Alone?

Confirmed deceased Home Alone cast members

• John Heard (played Peter McCallister) died in 2017 from a heart attack (Wikipedia (film cast)).
• Roberts Blossom (played Old Man Marley) died in 2011 at age 87 (Wikipedia).
• Catherine O’Hara (played Kate McCallister) is the most recent, as of 2026.

Clarifying alive actors often mistaken as dead

• Macaulay Culkin (Kevin) is alive and well.
• Joe Pesci (Harry) is alive.
• Daniel Stern (Marv) is alive.

The catch: internet searches for “Home Alone death” often return confusion with the historical figure Catherine the Great. O’Hara’s death is entirely unrelated to that query.

“Catherine O’Hara died of a pulmonary embolism, with rectal cancer as the underlying cause, according to the death certificate.”
— Los Angeles Times, Feb. 9, 2026 (Los Angeles Times)

For fans and the medical community, the takeaway is stark: a pulmonary embolism, often called a “silent killer,” ended the life of an actress who brought joy to millions. The National Blood Clot Alliance emphasizes that cancer patients should be aware of clot warning signs — sudden shortness of breath, sharp chest pain, rapid heart rate (National Blood Clot Alliance). O’Hara’s death, while heartbreaking, may save others by sparking conversations about a preventable complication.
