Summary
Ontario’s economic struggles, which are most dramatically illustrated by its transition to a “have-not” province, have implications far beyond the borders of the province. For the better part of a decade, and particularly since the recession of 2008/09, Ontario’s economic performance has dragged down that of the national economy. Due to both the sheer size of Ontario’s economy and its population, as well as the fact that the Canadian economy is highly integrated, what happens in Ontario influences our national economy.
The important influence of Ontario on the national economy is borne out by statistics. For example, if we compare the variation in per-capita GDP growth for Canada (without Ontario) against the variation in Ontario for the period from 1982 to 2012, we find that the variation in Ontario explains roughly three quarters of the variation in the rest of the national economy. Simply put, for the better part of three decades, the success of Canada’s economy was inextricably linked with the success and failure of Ontario’s economy.
Ontario’s influence is also seen in employment statistics. About two thirds of the variation in employment growth in the rest of Canada between 1982 and 2012 is explained by the variation in employment growth in Ontario. In other words, Canada experienced strong employment growth when Ontario experienced strong employment growth, and vice versa.
