What happened in May 2017?Who can solve this mystery?

-Futures curve flipping from contango to backwardation? No, that happened in October 2017.
-Widening WCS/WTI spread? Even though it doesn't affect CPG, could it be that negative sentiment towards all Canadian energy stocks brought down CPG too? Alas, no, this widening started occurring at the end of 2017.
