Peter Wallace will be replacing the outgoing city manager Joe Pennachetti in July.
City council unanimously voted to appoint Wallace to the job on Tuesday.
Wallace has a long career in public service.
A news release issued by the City of Toronto indicates that he began working for the Government of Ontario in 1981 and later ascended to a number of senior positions.
Pennachetti had originally been set to retire earlier, but stayed on at the request of Mayor John Tory.
He will wrap up his role on Friday. John Livey, deputy city manager, will serve as the city's interim manager until Wallace takes over the role in July.
