Paul Ainslie (/ˈeɪnzli/ ⓘ AYNZ-lee; born February 4, 1967) is a city councillor in Toronto, Ontario, Canada.

On February 1, 2006, City Council appointed Ainslie to fill the vacancy in Ward 41 that was created when Bas Balkissoon was elected in a provincial by-election in the riding of Scarborough—Rouge River.

However, when councillor David Soknacki announced his intention not to run in Ward 43, Ainslie put his name forward as a candidate to replace him.

[citation needed] During the election campaign in 2006, a video surfaced which showed Ainslie promising to Toronto City Council not to run.
