Maple Eight
Largest Canadian pension funds
From Wikipedia, the free encyclopedia
In Canada, the Maple Eight are the eight largest pension funds. The investment approach used by the Maple-8 is known globally as the 'Canadian model', in which they utilize a direct investment approach and internally manage their own assets and portfolios. Collectively, as of March 2025[update], the pension funds control approximately CA$2.4 Trillion[1] in assets under management (AUM), and they are heavily influential in Canadian and global investment markets.
The Maple-8 members
- The $179.6 billion (December 2024) managed by AIMCO includes (at that date) the $25.0 billion Alberta Heritage Savings Trust Fund – a sovereign wealth fund which is not supported by employee/employer pension contributions nor used for ongoing pension plans; see linked article for information about that fund.[11]
History
In 1986, when the Government of Ontario sought to improve its public sector pension plans, investment strategist Keith Ambachtsheer recommended Peter Drucker's model, as outlined in his 1976 book, "The Unseen Revolution”.[14][15]
Drucker posited creating a more diversified, globally oriented investment portfolio, handled by hired, not appointed, non-political professionals who received competitive remuneration, would lead to higher returns. The Ontario Teachers' Pension Plan was the first to adopt the model in 1990. In 2012, then president of the Canada Pension Plan Investment Board, David Denison, stated:
Canada’s system was ranked fifth best in the world in the Mercer Global Pension Index study for 2011. In truth, Canada’s high ranking has more to do with the woeful state of many other countries’ retirement systems than the robustness of our own.[16]
He added that there was room for improvement but the Maple-8's sophisticated, in-house investment model saved money.[16] In 2017, Ambachtsheer stated that the costs are average but the Canadian model generates a higher 10-year return compared to other funds.[17] At a 2024 symposium, OMERS president, Blake Hutcheson, stated the top Canadian pensions were not a monolith, as suggested by the term 'Maple-8,' and each investment board was unique.[18]
In 2025, Mercer ranked Canada's system at 17th with a B-rating, down from 12th in 2023.[19][20]
The term 'Maple-8' evolved from an article in The Economist titled "Maple Revolutionaries" which originally discussed the Top Ten pension plans in Canada. Due to their size, the Ontario Pension Board (OPB) and OPSEU Pension Trust (OPTrust) are not included in the Maple Eight.[21]
In November 2025, Prime Minister Mark Carney signed an investment agreement with the United Arab Emirates, and stated representatives of Canadian pension funds, with their $2 trillion in capital, would visit the UAE in 2026 to deepen existing partnerships in sectors such as energy, infrastructure, and AI.[22]
Canadian allocations
There has been much focus on the Maple-8's allocation to Canadian investments. Although the federal government is not involved in the operation or investment strategies of these funds, they have expressed a desire to allot more capital to Canadian investments, with suggestions of a minimum allocation. Pensions argue that their global investment strategies allow them to stabilize their returns, discovering alpha in other markets and hedge against any volatility in the Canadian market, while bringing international capital into Canada.[23][24]
