Both opposition parties are thanking the premier for his years of public service, but they're also urging him to reconsider proroguing the legislature.

PC leader Tim Hudak reacted to the news that Dalton McGuinty is stepping down as Liberal leader and premier. Hudak recalled the day 17 years ago when the two of them met at Queen's Park.

"Dalton McGuinty actually walked across the floor of the legislature, walked up to the back row and shook my hand," Hudak says.

He said that while the two of them haven't always agreed on issues, he has never doubted McGuinty's dedication.

Hudak then switched gears saying now is not the time to prorogue, when the province is falling behind and needs to keep working on issues like employment and debt.

"We just can't simply close the doors and lock them up at this crucial point in our history," Hudak says.

He also says that while the contempt motion over the gas plant cancellations is killed by prorogation, the issue is not over. Hudak says his party will bring the issue back.

NDP leader Andrea Horwath echoed Hudak's disapproval of proroguing the legislature.

And she says the "timing is curious" considering the contempt motion is currently on the table.
