The Canada Pension Plan Investment Board and Brookfield Asset Management Ltd. are jointly launching a $50-billion “Maple Fund” that will make major investments in infrastructure and key sectors in Canada, two sources said Monday.

Brookfield and CPPIB will each put up as much as $25-billion over the next five years to make equity investments in sectors that Canada considers strategic, as well as critical infrastructure projects, the sources said.

The Globe and Mail is not identifying the sources because they are not authorized to discuss the agreement publicly.

Spokespeople for CPPIB and Brookfield each provided statements from their respective CEOs that confirmed plans for the fund when The Globe contacted them for comment, but did not offer details.

“Canada is entering a period of new ambition to advance major projects and build for the future, creating compelling investment opportunities across the country,” CPPIB chief executive officer John Graham said in an e-mailed statement.
