Elections Ontario has launched an interactive video on its referendum website, www.YourBigDecision.ca. The online video uses various actors/ordinary Ontarians who walk viewers through the referendum question, the two electoral systems you are being asked to consider and what to expect on October 10th when you go into the voting booth.
It's nicely produced. The content matches the explanations already present in written format on other pages on the site, but does so using actors who do a good job presenting the basic facts about the referendum question. It's also available in closed captioning.
