TORONTO (AP) — The leader of Alberta's Wildrose Party says he's boycotting Tim Hortons to object to the coffee chain pulling ads for pipeline giant Enbridge from its in-store TV channel.

Brian Jean said Friday that he'll frequent the popular chain if the company decides to apologize for taking jabs at the oil and gas industry.

Tim Horton's, owned by Burger King, pulled the ads earlier this week after about 29,000 people signed an online petition asking the company to sever ties with Enbridge, the company behind the Northern Gateway pipeline project.

By Thursday afternoon, the top-trending Twitter hashtag in Canada was #BoycottTims.

Michelle Rempel, another Calgary Member of Parliament, supported the calls for a boycott. Defense Minister Jason Kenney tweeted that he's proud to represent thousands of constituents who work for Enbridge.
