TORONTO - The Ontario legislature has adjourned a day early -- an unexpected move that's left opposition parties fuming.

Progressive Conservative House Leader John Yakabuski says there's no reason to prorogue the legislature, especially without any notice or explanation.

He says the governing Liberals are ducking the last question period during which opposition parties can hold them to account before the election.

The early end of the session also means several private member's bills -- including one to make carbon monoxide detectors mandatory in all homes in Ontario -- will now die on the order paper.

New Democrat House Leader Peter Kormos says the premature end to the session shows the government's fear of having to defend themselves for even one more day.

The Liberals, however, say they have accomplished a lot over the session, and that Ontarians should be focusing on the legislation that was passed, not on the exact day the house rises.

The change in dates pre-empts a farewell planned for Speaker Steve Peters, who will not be running again in the next election.

But the session did end with a paper slide -- a long-standing parliamentary tradition where reporters who cover the legislature marked the end of the session by throwing papers over the edge of the gallery to the floor of the chamber.
