TORONTO, Nov 9 (Reuters) - Canadian home-improvement retailer and distributor Rona Inc, which earlier this year rejected a takeover offer from U.S.-based rival Lowe's Cos Inc, said on Friday that Chief Executive Robert Dutton was stepping down, a surprise move that came two days after disappointing results.

Rona said Chief Financial Officer Dominique Boies would serve as acting CEO while the company looks for a successor. Rona shares jumped amid speculation that the Quebec-based company might be in play.

Fund manager Irwin Michael, whose I.A. Michael Investment Counsel Ltd is one of Rona's top shareholders, said Dutton's "completely unexpected" departure gives the company a chance to rethink its plans.
