Ontario's minimum wage would be $10 USD an hour, lower than quite a few US states.
And prices might be in CAD, but Canada has a higher cost of living than the USA. Some examples with prices in USD -- Rent on a dingy 1-bedroom apartment in a medium-sized city in Ontario will be about $800 USD/month. Gasoline is $3.90 / gallon currently. Chicken breast costs about $4 / lb.
And that's to be afforded on a $10 USD wage. The minimum wage here is not a living wage. Workers have every right to be upset with that.
