It was because of the holiday, had he sat out yesterday, tomorrow, Wednesday... you wouldn't hear much more save for some fools. You're usually on the PR side of things, why are you missing the point? Prairies got you bitter, mate, lol.
FYI...
Victoria Day is a federal Canadian public holiday celebrated on the last Monday preceding May 25, in honour of Queen Victoria's birthday. As such, it is the Monday between the 18th to the 24th inclusive, and thus is always the penultimate Monday of May.
