The average hourly wage in Alberta is $27.55 and in Ontario it is $24.35. This is a 13% difference.
According to your numbers Ontario budget is $9382 per person and Alberta is $10683 per person. This is also a 13% difference. As labor costs only account for half of the difference, is it safe to say that the other $650 per person or $2.5 billion is a spending problem?
