Manitoba's Attorney-General has introduced a motion urging the federal government to begin consultations with provinces with the aim of abolishing the Senate.
Andrew Swan says Manitoba's position includes the results of public hearings which took place in 2009 that heard overwhelming support from Manitobans for outright abolishment or reform.
The motion states the Senate too often serves partisan objectives rather than public interest and that any confidence Manitobans had in the Red Chamber has been shaken due to the events of the past year.
In August, Manitoba made a submission, known as a factum, which addressed the constitutional questions posed by the federal government to the Supreme Court of Canada.
The province's position was that Parliament does not have the constitutional authority to enact significant unilateral changes to the structure of the Senate or to the selection of its members.
A vote was expected in the legislature later on Tuesday.
