Three observations
Interesting and surprising Quebec City is not on list of top ten high earners; perhaps not good news for Quebec NHL team aspirations.
Surprised at gap between Montreal and Toronto . To think they were "even up" at one time. Wealth and true value creation in Montreal would help our Canadian economy.
Resource industry wealth creation. I read some of the comments that would say " this is an aberation" , that since the oil price collapse , this chart probably looks different ( Vancouver back into third spot?)  but its hard to deny that resource industry is an important piece of our Canadian wealth creation pinging right down to T-4 income .
