U.S. based Circuit City has put its Canadian chain of stores up for sale, citing, among other reasons, the tens of millions of dollars it was forced to spend in re-branding. Circuit City acquired the chain of stores formerly known as Radio Shack in Canada three years ago. Following completion of that transaction, they were forced to change the name of the stores to The Source by Circuit City. As well as the large re-branding costs incurred, other reasons cited for the sale include increased competitiveness and shrinking margins in the consumer electronics business, difficulties in changing the focus of the types of merchandise offered and Circuit City’s own difficulties in the U.S. market.
