TORONTO (AP) — Canada’s Natural Resources Minister said Friday he’s “more confident” the Keystone XL pipeline will be approved after U.S. State Department’s latest environmental report raised no major environmental objections to the long-delayed project.

Joe Oliver urged the Obama administration to make a “timely decision,” noting the United States has been studying the pipeline for five years. He said the latest federal study was the fifth on its environmental impact and said each report has stated that the pipeline would not adversely affect the environment.
