A new plan to help low-income Canadians will set a lofty goal of lifting more than two million people past the poverty line over the next 12 years, says a source familiar with the federal government’s long-awaited strategy.

If the federal government meets the ambitious target, it would push poverty rates in Canada to historic lows.

Social Development Minister Jean-Yves Duclos, the minister in charge of the plan, will lay out details Tuesday at an event in Vancouver — including establishing the threshold that defines poverty in Canada.
