There's another new faction in the Senate: the Progressive Senate Group - 2019-11-14

The Independent Liberal Senate caucus is disbanding today and all of its members are about to join a new entity called the Progressive Senate Group as the reorganization of Canada's upper house continues apace.
Dismantling the Liberal caucus in the chamber means the upper house will be left without a sitting Liberal senator for the first time since Confederation.
The interim leader of the group, New Brunswick Sen. Joseph Day, said the senators are united by a belief in liberty and equality and a commitment to a progressive vision of Canada, where the government has a positive role to play in advancing the public interest. Sen. Day said he hopes other like-minded senators will join the Progressive ranks now that his group has dropped the "Liberal" label.
