I disagree with the metrics here. In the US Hydro power is not considered renewable yet it powers roughly a third of Canadians. Quebec's Hydro Power also powers a large part of New York, Vermont and Massachusetts.
I think they're focused on newly-built renewables rather than hydroelectric which was built decades ago by massive government subsidy and seems unlikely to see real expansion given environmental concerns re: fish spawning, etc.
In British Columbia over 50 new hydro electric plants have been built in the last 30 years by private industry. People may say they are subsidized since they often get $100/MWH for the first 30 years of operation but that is the price that must be offered to mobilize investment and it isn't much higher than the projected construction cost from the site C dam which would have much better economies of scale and the Construction cost doesn't include the 30 years of studies and consultation BC hydro did whereas that is covered by the 100$/MWH for the private hydro plants.
