Well, Heyu1960 step back...and ask: so, why would TransCanada be welded (pun intended) to pipe, especially when--for whatever reason--it's becoming soooo socially distasteful?  That--and broadening the business base, is why a pipeline company might diversify. 

Walt Disney: movies.  Then, theme parks.  Then, cruise ships.  Apple: computers, then--among other things--music service, which is software application, not even hardware! Ikia: furniture, right?  Walk into the store today--pick up...appliances. That last example is pretty much a no-brainer.  Twenty years from now, someone might say the same thing about the newer iteration of TransCanada.  TransCanada: funny name, that, when a huge chunk of its resources is allocated to a pipeline across...the U.S.  You go where the markets and money are.
