I think Elections Canada has a role to play, but I doubt it's the leader. Elections Canada's role is to ensure that electors understand the various voting options available to them.
We could discuss at length how to motivate electors to vote, but that gets a bit delicate for an electoral agency. It's very hard to motivate electors to vote without discussing the issues. When electoral agencies start discussing the issues, they immediately expose themselves to being perceived as being involuntarily partisan.
