Couillard is playing right into the hands of Trudeau, who would be more than happy to play the long standing Liberal tactic, the social unrest card, and enflame the  perceived Quebec versus Canada issue.  It always ends with the well documented Liberal response of buying Quebec off. This, in turn, rattles the western provinces, which Liberal governments do not care about as this is not part of their voter base.  
  An issue dormant these last 11 years as a result of the Harper government's nation within a nation domestic policy, one of the former PM's great achievements.  Stand back and let Quebec run itself with the funds it has available to do so.

To put it into perspective for Couillard, the Liberals regard Quebec as their fiefdom and the Premier as one of 10 provincial functionaries.  That is the price of the buy off.

No good will come of this.
