Discount Store News reports that “48 Towers due for remake.”  The March 4, 1991 article goes on to detail the conversion.

“Zellers plans to complete the conversion of 48 Towers stores by April 17, according to John Urie, executive vice president.

All but three of the original 51 Towers stores acquired by Zellers' parent, The Hudson's Bay Co., from The Oshawa Group, last October are currently being renovated to conform to the latest Zellers prototype. Urie projected that sales at these stores will rise substantially. "We expect these stores to show double digit percentage increases," Urie noted. The conversion will bring the total number of Zellers stores to 266.

While the total cost of the renovation was not disclosed, at the time of the acquisition, Gary Lukassen, executive vp and chief financial officer at Hudson's Bay, estimated that it would run into "several hundred thousand [(dollars)] per store."

The renovations are extensive, involving fixtures, aisles, decor and entrance location "The front purchase pathway needs to come out from the main entrance," Urie said. "In very few instances, entrances will need to be changed."

The simultaneous conversion of 48 stores is said to be manageable for the chain because, "We've had a lot of experience renovating many of our own stores," Urie said.

Consumers are being prepared for the changeover from Towers' to Zellers' format by advertising circulars promoting a "Renovation Sale."

One of the remaining three Towers will become a The Bay department store; the fate of the other two is up in the air.”
