Can you guess which one? If you think it's the one embroiled in a violent crack cocaine scandal, you are wrong. It's the other major Canadian mayor making headlines recently. Interim Montreal mayor Michael Applebaum resigned one day after he was arrested at his Montreal home by UPAC, Quebec's anti-corruption police division. Applebaum is facing 14 charges of fraud against the government, breach of trust and conspiracy and municipal corruption, among other things, from his time as Montreal's Côte-des-Neiges–Notre-Dame-de-Grâce borough mayor. 

"Being mayor of Montreal is not something one can do while defending themselves against these accusations. This is why I am resigning as mayor of Montreal," Applebaum told reporters. His predecessor, Gérald Tremblay, resigned over corruption charges in November. Applebaum campaigned to city council that he would fight corruption. Seriously, you can't make this stuff up. 

Rob Ford, the Toronto mayor accused of smoking crack cocaine, unveiled an Ai Weiwei exhibit in Toronto on Tuesday afternoon. He's still in office.
