The implication: her public footprint is clearly defined by political roles, with financial and personal details kept off the record.

Who is Bonnie Crombie’s husband?

Public records and news profiles about Crombie do not identify a husband or partner. Her personal life remains largely private. The Library of Parliament (official biography) lists only her professional history and birth details.

The pattern: this absence of family data reinforces a deliberate separation between her public and private life.

Bonnie Crombie daughter

Similarly, no source names Crombie’s daughter. References to her children are absent from the coverage examined — an intentional privacy boundary that aligns with her guarded public image.

The gap

What bio pages leave out is often as revealing as what they include. In Crombie’s case, the absence of family details suggests a deliberate separation between her public and private lives.

What is Bonnie Crombie’s net worth and salary?

Neither Crombie nor any official biography has released salary or net worth figures. Her occupations — public affairs consultant and politician (Library of Parliament) — don’t come with mandated personal disclosure of assets in Canada at the municipal level. Her mayoral salary would have been public in Mississauga’s budget, but exact living expenses or savings remain unknown.

The catch: without formal disclosure rules for municipal leaders’ net worth, any estimate is speculative.

Bonnie Crombie salary

  • No specific salary disclosed in the sources reviewed.
  • As mayor, her compensation was set by city council, but current figures are not cited in available materials.

Is Bonnie Crombie related to David Crombie?

No evidence ties Bonnie Crombie to former Toronto mayor David Crombie. The surname is coincidental; the two have never been linked in official records or news coverage. Verified by CBC News reporting that profiles her family background without mentioning David Crombie.

Bottom line: The name overlap creates a natural question, but the political records show no family connection between Bonnie Crombie and former Toronto mayor David Crombie.

How old is Bonnie Crombie?

According to Library of Parliament records, Bonnie Crombie was born on February 5, 1960, in Toronto, Ontario. That places her at 66 years old as of mid-2026. Earlier online searches sometimes listed her age as undisclosed, but the parliamentary source is definitive.

The implication: this clears up a common question in search results.

What is Bonnie Crombie doing now?

As of mid-2026, Crombie is a former Ontario Liberal leader who stepped down after the 2025 provincial election and a subsequent leadership review. She received 57 percent support in that mandatory vote (CBC News) before resigning. Now she is weighing a return to municipal politics: CityNews Toronto reports she is considering a mayoral campaign in Mississauga in June 2026.

The pattern: A move that would mark her second act in a city she already ran for a decade.
