The Ontario Liberal leadership race became a little more crowded Saturday with former cabinet minister Charles Sousa throwing his hat into the ring.

“I will be seeking the leadership of the Ontario Liberal party,” Sousa said at Mississauga’s Oasis Convention Centre.

During his speech, Sousa pledged to have Metrolinx become responsible for the TTC to speed up transit integration.

He said his focus as premier would be on creating jobs, especially in the auto sector and in the province’s north. Sousa said he would build mining and refining plants in Ontario.

“I believe in a government that nurtures the values of hope, prosperity and fairness,” Sousa said.

“I believe in a government that is fiscally responsible, socially conscious and builds for tomorrow. These are the values that guide me and it’s the desire to give back to Ontario that motivates me.”

The MPP resigned as minister of citizenship and immigration and the minister responsible for the 2015 Pan and Parapan American Games on Friday.

Sousa, who represents Mississauga South, was first elected in 2007 and has previously served as minister of labour.

Before jumping into politics, Sousa worked at the Royal Bank of Canada Financial Group for more than 20 years, according to his MPP website. Before that, he owned and operated a factoring company that offered financial services to small businesses.

Sousa holds a B.A. from Wilfrid Laurier University as well as an Executive M.B.A. from Western University.

He and his wife Zenny have three children.

Sousa is among the candidates vying to replace Premier Dalton McGuinty, who stepped down as party leader on Oct. 15, the same day he prorogued the legislature. The Liberals were facing a second contempt motion over the two cancelled power plants that cost taxpayers at least $230 million.

Dr. Eric Hoskins, who represents the Toronto riding of St. Paul’s, is expected to make a leadership bid next week. He resigned as minister of children and youth services on Friday.

Other official candidates include Kathleen Wynne, Glen Murray and Sandra Pupatello.

Those interested in joining the race must submit their names to the party by Nov. 23.

The fee to enter is $50,000 and candidates can spend up to $500,000 on their campaign.

A new leader will be chosen during a convention the weekend of Jan. 25, 2013.
