Historically, electricity has been a guarded fiefdom of the provinces. Where there have been opportunities for interties, we have exploited some and not others.
One example is the long, decades-old conversation around further Atlantic Canadian electricity integration. Following on the comments of Mr. Martin, I would say that a barrier that prevented the maritime provinces from further integrating their power systems was purely a protectionist notion. They were trying to avoid job losses, which means efficiency gains, within their own jurisdictions. As a consequence, although there is electricity trade among the maritime provinces, it is not nearly as beneficial as it could be if looked at from the perspective of the customer, rather than the interest groups that feed off the customer's money.
The federal government could go a long way in encouraging the provinces, where there are efficient opportunities, to put customers first and encourage the kind of integration that could reduce the inefficiency of power systems. I am thinking particularly of Atlantic Canada, and also the B.C.-Alberta interconnection.
In the case of the Ontario-Quebec interconnection, Quebec's best customer for electricity, historically, was the U.S., and that's certainly the case today. Ontario has very extensive electricity interties with Quebec, but they are mostly underutilized. They are utilized primarily for reliability purposes.
