On May 29, the British Columbia Green Party announced that it will work with New Democratic Party legislators to organize the provincial legislature. See this story. No party has a majority, so it was up to the Greens to decide whether to choose the NDP or the Liberal Party.
On Wednesday, May 31, the two governing parties will announce what they have decided about electoral reform.
Coalition government?
No.
As stated in the linked article it is Confidence and Supply which is a totally different arrangement from a coalition.
Wikipedia gives a bit longer description of that unfamiliar-in-the-US term than the article does: “A confidence and supply agreement is an agreement that a party or independent member of parliament will support the government in motions of confidence and appropriation (supply) votes by voting in favour or abstaining, while retaining the right to otherwise vote on conscience.”
It could be a great moment for BC, Canada and the rest watching if BC with its history of studying electoral syseith tems with citizen involvement and mostly positive results from voting on those measures to just make the switch away from FFTP; long overdue.
