Crime doesn’t pay, but jury duty should

A Canadian federal report recommends paying jurors at least $120 daily. Provinces should take action.

I'm glad Ontario will finally start paying jurors from day 1, but disappointed the $120/day rate remains below the $146 legal minimum any other employer must pay.

Governments shouldn't ignore their own labor laws.

By contrast, 8% more Canadians are flying overseas in 2025. It seems that about 70% of those who would normally fly to the USA flew overseas instead.
