After the attack on Mayor Dave Bronconnier, police quickly had the woman in handcuffs and off to jail.
"As a public servant, you try to be as accessible as possible," Bronconnier said in a news release.
"If people want to stop me on the street and talk, I'm always happy to do that, even if they don't agree with me.
"But this sort of behaviour is thoroughly unacceptable in a democratic society."
The Mayor escaped the pie attack with only a cut on his finger.
Earlier this week Alberta's Premier Ed Stelmach narrowly escaped a similar attack when Lily Phan tried to get him in the face with a pie after protesting about affordable housing.
Four years ago then-premier Ralph Klein was assaulted by a pie. His attacker served 30 days in jail.
Jean Chretien had pie face twice. Once in 2000 and again in 2003.
