Ottawa city council has voted 21-1 to approve a report calling for a new main library branch overlooking Lebreton Flats.
The library is to be built in conjunction with Library and Archives Canada, at a cost of 99-million dollars, just off Wellington near Bronson.
It's to open in 2022.
The lone dissenter was the Councillor who represents the area, Catherine McKenney.
She was concerned that, for Centertown residents, the move will mean they're losing their local library.
"It will be a hole in the community," McKenney told council.
"It's not just about whether one community is getting something and one isn't - one community is losing a library."
But Mayor Jim Watson says they will be looking for ways to serve those residents.
"What we can do to offer services, perhaps around the city hall area, or in other public access space, for people to come and do work in the library, whether it's con computers, dropping off books or picking up books," Watson said.
A poll commissioned by the Library board found 88% of those surveyed like the idea of a shared facility, and 72% approved of the site selected.
The Library board will now work on financing plans and a formal agreement with Library and Archives Canada - that will come back to city council in June.
