Techncially the right of way for an interprovinical pipeline is federally regulated and overseen by a private entity. Same with railroads. However, in practice it's difficult to go ahead without the provincial government (Enbridge, for example, requires dozens of provincial regulatory permits) and teh First Nations (who have no regulatory authority but pack a lot of clout in court).
Railroads, pipelines, and roads all require a physical presence. A presence that crosses provincial and First Nations jurisdictions.
The technology being studied removes that.
