His father is John Gerretsen, a long-time politician who served as the mayor of Kingston, a Member of Provincial Parliament (MPP) for Kingston and the Islands, and held several cabinet positions in the Ontario Liberal government, including Attorney General and Minister of Municipal Affairs and Housing.

Potential Conflicts of Interest

In 2018, the Ethics Commissioner investigated a complaint against Mark Gerretsen after he posted a video of a Conservative MP from a House of Commons committee meeting on social media for what were described as partisan purposes. The commissioner, Mario Dion, concluded that while the video was "highly partisan," it did not violate conflict-of-interest rules. The investigation found that Gerretsen did not use his position to improperly further his own private interests or those of his family or friends.
