From the article:
"All of the relative decline can be explained by what has happened in the factory sector.
Statistics Canada puts the manufacturing job losses in Ontario at 255,000 over the past decade, dropping the number of factory employees from 908,900 in January 2003 to 654,200 in September 2012.
Coincidentally, during an similar period, the province's gross domestic product output has swooned even further in relation to the national total from 41.4 per cent in 2002 to 37.1 per cent last year.
In both output and jobs, Alberta and Saskatchewan have been the key beneficiaries."
Alberta has very favourable taxation, no payroll taxes. Saskatchewan as well has no payroll taxes and both provinces have lower corporate tax rates across the board.
The dollar being strong certainly hasn't helped Canada as a whole, but the manufacturing and corporates have found better places in Canada to do business.
