Clearly, the short and long answer is no. If one looks, for example, at a situation in the power sector in Ontario right now, there is a private sector firm called Bruce Power that operates nuclear reactors in Ontario, under the regulation of the CNSC. It does so with the same safety standards as OPG, and Hydro-Québec and NB Power. So the short and long answer is no.
