Senate reform linked to constitutional agreement

In her article today, Chantal Hébert talks about the futility of trying to create Senate reform without addressing the constitutional process that is necessary to make changes, and the consequent need for most, if not all, provinces to agree on the precise change.

She also points out that a constitutional change is not required in order to implement proportional representation. So how about it, MP's? Could we have referendum at the next election on whether or not we want PR for the House of Commons?
