“That’s a constructive market as far as I’m concerned, especially in Canada, where materials are such an emphasis.”

Among the decliners, contract electronics manufacturer Celestica Inc. (CLS.TO) slid 3.7 percent to C$9.08 after reporting a quarterly net loss, hurt by higher restructuring charges. [ID:nSGE66M0EC]. That helped drag the technology sector down 1 percent.
In other company news, Magna International MGa.TO rose 1 percent to C$77.55 after the auto parts maker announced that three-quarters of its subordinate shareholders approved a deal that would pay founder Frank Stronach upward of $1 billion to effectively give up control of the company.
