Toronto’s old Mr. Christie’s bakery in the city’s west-end will be shut down in the fall of 2013, putting 550 employees out of work.

Owner Mondelez Canada announced Thursday that it will close the 625,000 square foot bakery at Lake Shore Boulevard and Park Lawn Road.

The facility has produced cookies and crackers since 1948.

Mondelez Canada said the facility’s aging infrastructure and residential development were behind the closure. The company said some production will shift to its East York and Montreal facilities and the rest will be split among its North American plants.

“This is a difficult decision, given the role this facility has played within our organization and in the community for 64 years,” said Alvaro Cuba, vice-president of operations for Mondelez Canada in a statement.

“However, the plant faces some unique challenges resulting from the changing neighbourhood surrounding the facility.”

The decision will affect some 550 employees.

“Our focus right now is on our employees,” Cuba said.

“We’re committed to treating our people fairly and working with them through this difficult time.”

The company said it made the announcement nearly a year in advance to provide a “smooth transition.”

Coun. Peter Milczyn said he will suggest to Mondelez to relocate the affected employees to other Toronto plants.

He added that the “city is not prepared to entertain a massive re-development at that property.”

“I will also be advocating that this location stays reserved as employment lands,” he said.

Mondelez was created from the spin-off of Kraft Foods Inc. in North America into Kraft Foods Group Inc. in October.
