It's one of the most ambitious makeovers at a Hamilton mall in quite some time.

Cadillac Fairview has submitted an application to the city's planning department that calls for a multimillion-dollar redevelopment of Cadillac Fairview Lime Ridge Mall, on Upper Wentworth, that includes 12 new buildings and nearly 200,000 square feet of new retail and commercial space.

The application was submitted on April 17.

According to the application, the former two-storey Sears department store on the north side of the mall will be torn down.

It will be replaced by more than 60,000 square feet of new retail space split between three units on two floors.

The plan also calls for five new restaurant buildings ranging in size from 6,000 to 7,500 square feet.

Three of those buildings are slated to go up on the west side of the mall facing Upper Wentworth.

The two other restaurants will be located on the top floor of a proposed 500-vehicle, two-storey parking garage that will go up next to the two-storey building on the former Sears section, and the plans call for both eateries to have outdoor patios.

In addition, Cadillac Fairview is looking to add another two-storey building with more than 65,000 square feet of retail space over three units next to the office building, which is currently home to radio stations K-Lite and TSN 1150.

There is no word on when the project might move forward.

City planner Melanie Schneider said the application has been put on hold pending more information from Cadillac Fairview.

Meanwhile, the company is not offering any more details on the proposal.

"At this time we are not able to comment any further," said Cadillac Fairview spokesperson Anna Ng.
