CUAP - Canadian Universal Ad Package
Phase One: Leaderboard (Superbanner), Skyscraper & Big Box

Background
Following the successful route that the American online industry has gone, a joint task force made up of both IAB Canada Publisher and Agency member reps began a process in 2004 to define a set of Canadian standard ad sizes, for the purposes of reducing the costs and inefficiencies associated with the planning, buying and creating of online media. The result was the creation of the Canadian Universal Ad Package (CUAP): a set of 3 standard ad sizes that both Publisher and Agency member reps have agreed to support.

Phase 1 of the CUAP sets the expectation that ads created to the new specifications will run on any "certified" IAB member site.

The three CUAP standard ad units (in bold), were taken from the roster of previously recommended units listed below. Detailed unit specifications can be viewed on the Canadian Universal Ad Package page.

Future phases of the CUAP package will cover rich media and video standards, as well as ad measurement guidelines.
