BMO Capital Markets has appointed Evan Siddall, the former president and chief executive officer of the Alberta Investment Management Corp. (AIMCo), as vice chair.
“We’re thrilled to welcome Evan Siddall to BMO Capital Markets as vice chair,” said the financial company in a post on LinkedIn. “[Siddall] brings a wealth of knowledge from the public and private sectors, most recently serving as president and CEO of Alberta Investment Management Corp. Along with his extensive leadership experience, [Siddall] has a strong commitment to community involvement, reflecting the core values we share at BMO.
In his new role, Siddall will partner closely across the organization’s capital markets, strengthening and driving connectivity across product offerings and client services, noted the post.
Siddall’s extensive career includes spending three years leading the C$175.6B AIMCo, one of Canada’s largest “Maple Eight” pension funds. He was also a non-resident senior fellow at the Brookings Institute and president and CEO of the Canada Mortgage and Housing Corp. for seven years. He also served as special advisor to the governor of the Bank of Canada for nearly three years, as well as spending three years at Irving Oil, first as a corporate finance director and then as an advisor to the CEO. His earlier roles include senior positions at Irving Oil, Lazard, Goldman Sachs, and BMO Nesbitt Burns.
In November 2024, the Alberta government dismissed Siddall and AIMCo’s entire board, citing rising costs. Since then, the province has been rebuilding the organization’s leadership. In November 2024, Ray Gilmour was appointed interim CEO and former Canadian Prime Minister Stephen Harper became board chair in January 2025. Sandra Lau, AIMCo’s former CIO and head of public investments, joined the board in June 2025, and Justin Lord was appointed CIO in July 2025.
