Hi Bev, WELCOME TO THE CDN BOARDS!
The Canadian ticket deal is buy one 7 day hopper plus pass and get the companion pass at have price. Right now 7 DHP are $471 for adults, so the deal is buy one at $471 and the second is $235.50. Thing is, they expire. But they do have a long usage time. Usually around late Sept, early October we'll start seeing ads in the papers travel section for these tickets. You can start buying them mid November and use them up to late April or early May when they expire. We have purchased these tickets two years in a row since we like using all 7 days at the parks and stay for 10 or 11 days. We get to relax and enjoy everything DISNEY! Hope that helped! S
