(AP Photo/Nati Harnik, File)TORONTO – Top officials in Canada want a chance to make the case for a long disputed oil pipeline to be built amid reports President-elect Joe Biden will cancel Keystone XL. Canadian Prime Minister Justin Trudeau raised Keystone XL as a top priority when he spoke with President-elect Biden in a phone call in November. The project is meant to expand critical oil exports for Canada, which has the third-largest oil reserves in the world. Trudeau and Biden are close and largely politically aligned, but the pipeline is expected to be an early irritant as Biden has said he would cancel it.
