On the topic of Hydro Québec, there's just something about the scale of turning the fifth largest asteroid impact crater into a reservoir for hydroelectricity that is awe inspiring. Why don't we see those sorts of aspirational mega projects for the greater good in Canada anymore?
I think the stars have to be aligned for a project like that to work. You need buy-in from first-nations, a charismatic PM that won't get thorn apart for spending prodigious amount of money and general public goodwill towards the objective.
