The New Democrats are introducing an opposition day motion after an ipolitics.ca report said Prime Minister Stephen Harper has transported a family friend and fundraiser between Ottawa and Calgary.
New Democrat ethics critic Charlie Angus is holding a press conference at 9:30 a.m. ET to discuss the motion.
The Conservatives say they have reduced the use of government jets since taking office.
The motion calls for MPs to agree that "government planes, and in particular the plane used by the prime minister, should only be used for government purposes and should not be used to transport anyone other than those associated with such purposes, or those required for the safety and security of the prime minister and his family."
