Gad, who knows. I'm not schooled in the dark arts. Ontario isn't due until June. Current pandemic; concerns of 4th wave, BC fires, typical avoidance of a 'depth of winter' election and on and on. It does leave them next March/April, but who's know how the backroom strategizes things like polls, opposition positioning, pre-election largesse timing, etc.
If the numbers are in their favor, I can see the liberals pulling the plug.
