An analysis of long-term trends suggests that Canada's East-West economic divide will only deepen in the next 10 years.

TD Bank economists project the next decade will see a continuation of economic power gravitating West, in large part because of the migration of labour to resource-rich Alberta and Saskatchewan.

In effect, this is a continuation of a trend that's been going on for some time.

But the analysis suggests that the economic divide will deepen, with the spread between have and have-not provinces increasing.

That's a reversal of the convergence in economic performance that had been under way since 1990.

TD says Alberta will lead average growth at 2.5 per cent, while Quebec and the four Atlantic provinces trail at less than 1.5 per cent.
