Toronto's crowded brewpub market is losing most locations of a giant  chain.

Canadian Beer News reported that 3 Brewers will be shutting down all its locations in Toronto except for one. That includes the Financial District and Liberty Village locations. 

Richmond Hill and Mississauga locations will also close but the Oakville 3 Brewers will remain open.

"Ten years ago, we entered the strategic market of Ontario and, over that time, experienced some great victories, notably our Yonge and Oakville restaurants, but also some challenges," said Laurens Defour, CEO of 3 Brewers Canada, in a statement.

"This is a difficult decision, but we have concluded that we need to close some sites in order to support the evolution of our business."

The chain is known for brewing beer on site and serving it alongside hearty pub eats. The last day of operation for the four locations of 3 Brewers that will be closing in Toronto will be December 31.

The Yonge and Dundas location is the only one that will remain open.
