Phillips represented the riding of Scarborough-Agincourt for 24 years.

The MPP said he went to Premier Dalton McGuinty last August with his decision but made the final call this week.

"I have actually enjoyed every day of this job serving my constituents and the people of Ontario and I hope making a positive difference in their lives. Having that opportunity is an honour and a privilege," Phillips said.

"But it is also very demanding. It deserves a level of daily intensity that I am not convinced that I can commit to for the next four years."

Phillips was first elected to the legislature in 1987 and held several cabinet positions under McGuinty and former premier David Peterson. He is currently a minister without portfolio.

Phillips's announcement brings to 10 the number of sitting Liberal MPPs who will not run again in the fall campaign.

Others include Speaker Steve Peters, deputy Speaker Bruce Crozier, government house leader Monique Smith and members Pat Hoy and Jim Brownell.

Former labour minister Peter Fonseca is leaving provincial politics to run federally.
