The work will be done between Jarvis Street and the Don Valley Parkway along the highway’s southern barrier wall.
Last year chunks of concrete from the Gardiner came crashing down onto Lake Shore Boulevard from the overhead expressway.
The city officials say they'll be in a better position to figure out what to do with the Gardiner once an environmental assessment is completed, but that could take more than five years.
Coun. Denzil Minnan-Wong, the chair of the city’s public works and infrastructure committee, said earlier this week that residents will have to be patient about the delays the repair work will create.
"This investment in the Gardiner Expressway will ensure the section of roadway is in a state of good repair while decisions are made on its future," Minnan-Wong said.
