RTTI is a service of Clear Channel Communications, the people that own radio stations in major US cities and torture us with Britany Spears tunes every 17.2 minutes. The traffic information is broadcast using the guardband on the frequencies they own in heavily populated areas. I am not sure if Clear Channel owns any radio stations in Canada. If they do, then RTTI will probably make its way up north eventually. If not, you may be out of luck.
