Brad Woodside says he will run for the mayor of Fredericton in 2016 afterall.

Woodside indicated earlier he would be on the ballot in May's municipal election, but was undecided about running for mayor or for a seat on city council.

On Thursday, Woodside put the mystery to an end, tweeting that he would run for mayor.

"I've decided to spend the last of my working years doing what I love most, being your Mayor," said Woodside in a tweet with the hashtag #BradforMayor.

Mike O'Brien, who has been the city councillor representing the ward where Woodside lives, has also declared he will run for mayor.

A third candidate for mayor is Malcolm Cumming.

In 2012, Woodside had declared that campaign would be his last for mayor.
