The screen shot that you've posted is the broad search results. If you click on exact it drops down to 74,000 global exacts which are still great. Local exact monthly searches are 880 (for Canada).
The exact searches are likely because;
1) dr1.com is a developed site that people want to go to. It's developed as Dominican Republic site.
2) DR1 is a Danish national TV station
So those search results aren't as helpful to your .ca domain as they first appear.
If you develop it of course the domain can become worth something. As it is, it isn't worth much to a reseller. There are still a lot of LLN.ca domain available.
