Different results on google.com/.ca

Im in Canada and for some reason my site is only visible on google.com and not on google.ca. I can't access the .com directly with out having to go through a proxy site because google recognizes my ip as canadian and sends me to the .ca

How can I control this so my search results are visible to both .com .ca and whatever other ones there is? Do I have to submit to each of them separately?

Thanks

 

This is strange, but probably yes - you should get backlinks from servers with both tld's.

 

Google's search results depends on many factors (geolocation, browser settings, search preferences, etc.) and what you are talking about is normal.

 

There is no difference !
But google have domains according to the geographic locations !
