The Canadian Pension Plan Investment Board (CPPIB) manages a large and rapidly growing fund. The CPPIB however is accountable first and foremost to the federal and provincial governments, not the contributors and beneficiaries. Over the years, the CPPIB has moved from real assets to equities, and from investments in Canadian infrastructure to foreign investments. With over $539B of our public pension at stake, we need to be aware of what the CPPIB is up to.
