It's not a bug. It's not a defect. It's been mentioned before (A search performed with "google.ca" as the search terms yielded:
http://www.blackberryforums.com/gene...ght=Google.ca). All you have to do is scroll down on the Google.ca page and click on "show me Google US" (or something to that effect). DiRN is however somewhat correct. Google recognizes the phone's IP (I believe) as of Canadian origin, therefore it shows you Google.ca until you make the above mentioned change.
