In terms of electricity, there are enormous benefits to increasing the interconnections among the provinces and, ultimately, with the United States. The goal isn't so much to export net volumes of energy, but rather to exchange energy.
I disagree to some extent with Mr. Mousseau on one thing. Contrary to his assertion, Canada has a competitive advantage over other countries in the world. We have ample space, plenty of wind, a great deal of sun and many storage tanks. We have a competitive advantage because of our geography. This can help us produce more electricity at a lower cost.
The interconnections help us to exchange energy in order to optimize our production and consumption structures. This is where their benefits come into play. It isn't so much a matter of generating net exports, but rather of exchanging energy.
