The Canadian sub-domain briefly displayed a banner showing the words that BBM for android and iOS is here. This was however removed later and replaced with a banner showing that the Blackberry messenger app will be coming to Android and iOS soon.
This might mean that the new chat service is ready to launch and blackberry is probably waiting for the right time to launch the app. Soon we wont need to own blackberries to actually use the BBM service.
However, according to Engadget, the Canadian blackberry page showed some services that wont be included at launch such as BBM Voice, BBM Video and screen sharing features. The page was later on torn down and might reappear during or after the launch.
