Hi Tory.
Your .com site is viewed as a competing site. Even though you are both Travelocity, and clearly the same company, Google is viewing the two sites differently. The .com site is clearly more established, has a much higher Domain Authority and is outranking the Canadian site.
If you wish your Canadian site to outrank your .com site, then one thing you can do is to have your .com site use anchor text for phrases like "Canadian Travel" pointing to your site.
I would think there is more that can be done but I am not experienced in this area so I will let others chime in.
A few additional comments I would like to share.
-
Your .com site is very strong. You may want to consider using the one site and the canadian portion can be serviced with .com/ca
-
I notice you are using the /ca folder on the .ca domain which seems odd. travelocity.ca/ca
-
You are presently 302 directing traffic from travelocity.ca to travelocity.ca/ca. This should be fixed asap.
