The only election EVER fought on KM pipeline in BC was the 2013 BC provincial election. Was known as the "Kinder Morgan Surprise", which dominated latter half of campaign. BC NDP ran TV ads with oil tankers in Burrard Inlet opposing same.
Final outcome? BC NDP lost popular vote share in ALL 4 Burnaby ridings over 2009 election. Go figure.
2017 BC election? BC NDP leader Horgan told media that he "did not want to talk about KM". Wasn't an issue. At all.
In 2015 fed election? Local newspapers reported that candidates in all fed Burnaby ridings stated that KM was not even an issue at the door step.

Frankly, I'd wager that the KM pipeline would be a bigger issue in downtown T.O. riding of Toronto-Danforth than in Burnaby South.
PS. KM pipeline doesn't even run through riding of Burnaby South.
