Alastair Hall was named senior managing director and head of Europe at OMERS Infrastructure, an asset management unit of the C$105 billion ($82.1 billion) Ontario Municipal Employees' Retirement System, Toronto.
Mr. Hall is replacing Philippe Busslinger, who recently left OMERS Infrastructure, a spokeswoman said.
OMERS Infrastructure had C$30 billion in assets under management as of Dec. 31.
Mr. Hall, who is based in London, was OMERS Infrastructure's global head of investment strategy and partnerships. He will continue to oversee its strategic partnership program while a search for his replacement is conducted.
"Alastair is perfectly positioned to drive growth for OMERS Infrastructure as we seek to deploy significant amounts of capital and grow our assets under management in the region," said Annesley Wallace, executive vice president and global head of infrastructure, in a news release Monday.
Most recently, Mr. Hall focused on OMERS Infrastructure's global investment strategy and third-party capital program. Before that, he led investing in European energy, utilities and renewables.
