It is the trend that is being set. 

Fortis buys ITC for $11.8 B. Emera buys TECO for $6.5 B US$. Enbridge buys Spectra for $37 B. Altagas buys WGL Holdings for $4.6 B. TransCanada Corp. buys Columbia Pipeline for $13 B. 

On top of the there is the list of private infrastructure projects that were cancelled or stopped by JT's Liberals.  Petronas cancelled Pacific Northwest LNG, $36 B.  Enbridge has Northern Gateway wiped out by the Liberals, $7.9 B. TransCanada Corp cancelling Energy East, $16 B.   Shell's Carmon Creek, just to name a few. 

This isn't just coincidence, the current government and their new regulatory regime and climate policies have to shoulder much of the blame.
