There are reasons the option appears attractive. Quebec has an abundant supply of hydroelectric power, so there is the appearance of an opportunity. Additionally, the demand profiles of Quebec and Ontario could be considered complimentary: Quebec has a winter peak, and Ontario has had, in recent years, a summer peak.

Ontario has only had local calls for conservation over the past couple of years (Toronto area), but Hydro Quebec called for conservation during winter demand peaks in both 2013 and 2014.
Ontario's first (and only public) Integrated Power System Plan (IPSP), released in 2007, noted an additional 1250MW of "Quebec Interconnection" as part of supply intended to meet the desired "Renewable Resources Goal." That interconnection has since entered service. I have been tracking hourly intertie data back to April 2011; connecting that data with Ontario's top 25 winter, and summer, demand peaks shows that the flow of electricity between the provinces is exactly as logic dictates it should be.
