CAUCUS REVOLT: Tory MPs sign letter calling for leadership review of Erin O’Toole

The letter would require Conservative MPs to vote as soon as Wednesday's caucus meeting.

Sources told the Globe and Mail that at least 63 of the 119 Conservative MPs are ready to vote against O'Toole.

Two CPC sources have also confirmed to True North's Candice Malcolm that the vote count is over 60.

O'Toole has been the topic of much criticism in Conservative circles after weak messaging on the truckers convoy, though a source told CBC's Travis Dhanraj that the move to oust O'Toole as leader "stems from the conversion therapy vote," noting that "MP @GarnettGenuis is spearheading the coup because he was in Latvia when we gave unanimous consent to make conversion therapy illegal."

"So this was all started by the group that are internally referred to as the Conversion Crew. They're driving this,” the source said.

The source also told Dhanraj that former leader Andrew Scheer wants to be interim leader of the party.

According to the Canadian Parliament website, "a leadership review process may be initiated by submitting to the party’s caucus chair a written notice signifying this intention, signed by at least 20% of the party’s caucus "

"The caucus chair must make public the content of the written notice immediately upon its receipt. The leadership review is to be conducted by a secret ballot among members of a caucus.

"Where a majority of caucus members vote in favour of replacing a party leader, a second vote shall be conducted immediately following the first vote, by secret ballot, to select an interim leader until a new party leader has been “duly elected” by the party."

O'Toole's office has not officially commented on the letter.
