Brown, who served on city council from 2001 to 2006, ran against Lee in 2010 and lost by 3,000 votes. Brown announced his candidacy with a campaign video on Twitter Thursday morning. He believes he can beat Lee this time with what he calls a shorter and more concentrated campaign.

"We know it's going to be a difficult campaign because of his 30 years of service," Brown told CBC News.

"We have to, you know, try to put something in there that people can grasp, and I think this election we're looking at the issues that affect people directly."

Brown said his campaign will focus on four things: efficiency in council, property taxes, cosmetic pesticides and sewage and water problems.

Lee, the longest serving mayor in the history of Charlottetown, announced in late June he is planning to run again.

Election day is Nov. 3.
