The head of Caisse de depot says Canada's largest pension fund manager will unveil a new plan in the next few months to improve returns on its investments and support Quebec's economic development.

Caisse CEO Michael Sabia says change is needed because old strategies no longer ensure future success.

Speaking at a Caisse-sponsored conference on the future of Quebec businesses around the world, Sabia said the world has changed and so has the Caisse.

He says it has simplified its structure and investment strategy, distanced itself from complex derivatives, is more focused on its core skills and manages risk better.

This was all done to ensure the organization has a solid foundation to better serve its customers, Quebec public agencies that deposit their pension funds.

Sabia says the Caisse plans to leverage its own expertise and broad global network to advance the province's competitive advantage.
