Exclusive: Watch the entire 18 minute secretly taped video of Cal Wenzel talking to a meeting of developers

CALGARY- In an 18 minute secretly taped video of a meeting last November, Cal Wenzel, the founder of Shane Homes, presents developers and home builders with his plan to control city council by backing development-friendly candidates.

The person shot portions of the meeting on a cell phone and does not want to be identified.

As a result of this video, Calgary mayor Naheed Nenshi has called for an investigation into civic election campaign contributions.
