The Alaska natural gas pipeline must cross state, federal and Canadian acreage. The Office of the Federal Coordinator works with over 25 federal agencies, the Canadian federal government, the State of Alaska (land owner for the known North Slope natural gas reserves and owner of parts of the pipeline right of way), tribal governments and other stakeholders to expedite federal permitting and construction, as well as educate and inform the public about the project.
Here you can get more information about the Canadian regulatory process, the project in Canada, treaties and a link to the OFC's counterpart in Canada.
