I think it's fair to say that when you look at these provisions, they have both grandfathering and transition, the grandfathering so that projects already under way continue to receive the tax treatment, and then the transition over a fairly lengthy period so that the effect is phased in over time. Those were the same provisions that were paralleled in the oil sands industry when those were enacted in budgets 2007 and 2011.
Certainly the idea is to give the mining industry ample opportunity and time to plan for those changes and to not affect projects that are already under way, and in the recognition that, yes, mining is an activity that occurs in most provinces and territories across Canada, and often in those rural areas.
