Some politicians are floating the idea of Right To Work (For Less) in Canada.

This is an attack on the Canadian system of Labour Relations going back to 1946 when Justice Rand ruled that workers in a Unionized shop had to pay their share of the cost of Collective Bargaining. For more info see this previous post:
