Very simple. Every year, 1/6th of a province's Senators would have their terms end and their positions would become open.
Rather than appoint Senators, or even electing them, we pick them at random from all Canadians of voting age.
Canadians could decline the nomination, but random selection would ensure that real everyday Canadians would get to look over our laws and proposals and stop the more silly aspects of the more silly laws.
Since only 1/6th are renewed each year, there would always be a body of Senators with experience, and since 6 years would be a term, career Senators would be impossible.
