Sears Canada CEO Douglas Campbell has resigned after one year in the post, citing personal reasons.

Campbell, who will return to the US by the end of the year, will continue in the role until 1 January at the latest while the retailer searches for a replacement.

Sears Canada chairman William Crowley said Campbell "brought a focus on creating value for shareholders while taking the cost efficiency and investment steps necessary to produce a viable and profitable Canadian retailer".

Campbell is the second CEO to leave the retailer in just over a year, after Calvin McDonald announced his decision to step down last September.

US-based Sears Holdings is trying to offload its 51% stake in Sears Canada, and in May said it was exploring strategic alternatives including a possible sale.

Sears Canada last month revealed it had swung to a second-quarter loss of CAD21.3m (US$19.4m) from earnings of CAD152.8m a year earlier. Total revenues for the period dropped 11.9% to CAD845.8m, primarily due to store closures. Same-store sales were down 6.8%.
