No it doesn't.  At some point, unskilled work has a value, cross that value line and you get replaced with automation.  At $11.60, as of next month, that level of value has kept pace with inflation in ON.  
Raise the wages in the GTA to $17 an hour, but the rest of ON should not be anywhere close to $15.

Heck, raise the rate to double inflation, go up 4% per year VS 2%, not 32% in 18 months.
