Although considered a serious contender for the Ottawa mayoral elections this November, Coun. Peter Hume told CTV Ottawa he will not make an attempt for the position.

"I've come to the conclusion that it takes enormous resources to run a campaign for mayor, and I can't sustain a city-wide campaign that would bring me to an election," he said, adding he would stand for re-election in his ward, Alta Vista.

"So I won't be a candidate for mayor in this coming election."

In January, Hume said he wanted homelessness targeted as an election issue, with a question on the ballot asking residents if they are willing to collectively spend $5 million annually to end chronic homelessness by 2014.

Among the confirmed contenders for mayor are former MPP Jim Watson -- a one-time mayor of Ottawa -- and Coun. Alex Cullen.

Incumbent Larry O'Brien hasn't announced whether he will run again.
