In Ontario there are municipal referendums, but the question has to be approved by the Chief Electoral Officer. There have been some in our larger jurisdictions—the city of Toronto comes to mind.

These questions come from the municipal councils to the Chief Electoral Officer for the approval of the question, and then they're run at the municipal level.
