Saskatchewan Premier Brad Wall says it's time to push back against what he called myths being perpetrated about Canadian oil and a controversial pipeline that would ship oil from Alberta to Texas.

The premier said Canada's image and the country's trade relationship with the United States are not being helped by some of the debate.

Wall touched on the subject while speaking to a group of U.S. legislators in Charleston, S.C., about energy security and independence.  

He said Canadian oil is often cleaner, from a carbon standpoint, than oil from other countries.

He also criticized opponents of the Keystone XL project for "much myth making" related to the pipeline.

"Al Gore has said that that the oil inside the pipeline is 'the dirtiest source of fuel on the planet'," Wall said Friday. "His opposition echoes that of ill-informed celebrities and others."

Opponents of the Keystone XL pipeline say the project is an environmental disaster waiting to happen.

Advocates say the pipeline will create thousands of jobs amid a lingering recession and help end U.S. dependence on Middle East oil.
