Cregier lost his bid for reelection in the 1891 Chicago mayoral election. He had first seen Carter Harrison Sr. challenge him for the Democratic nomination. Cregier was able to win renomination over Harrison, as the local Democratic political machines had supported Cregier as they found him to be even more accommodating to them than Harrison had been.

Cregier's tenure as mayor ended on April 27, 1891. , mounted in 1933 in honor of Cregier's services.
