This seem to be the general consensus, but in reality the amount of content is only slightly higher on the US site. I don't know where this whole idea of Canadian netflix being so inferior to the American version even started. Most of the people who tell you that the American version has far more movies have never actually done a side-by-side comparison. There are probably over a thousand movies on netflix Canada. How many do you need? Let's say there are 1500 on the US site, I guarantee you wouldn't be interested in watching all of them. Just enjoy what we have here, it's hardly worth the effort.
The CRTC would like to thank you for your co-operation and hope you continue to enjoy their high quality programming such as The Littlest Hobo, Tommy Hunter and Littlest Mosque on Prairie. Now for the rest of us who do like choice I highly recommend that unblock us site, it's only 5 bucks a month, very easy to install, there is a Youtube tutorial how to do it and you can use it on your computer, PS3 or phone, it's just a case of switching the DNS numbers. Now not only does it open up the US Netflix but other nations as well, for example the Brazilian one has every James Bond film ever made up to Quantum of Solace.
I use this site to compare and see what movie is on which country's Netflix
www.moreflicks.com and go back to unblockus and just simply switch the country in the drop down bar, very easy,convenient and opens up all sorts of entertainment also like the online BBC Iplayer and ITV sites available only to UK viewers. I been doing this for about 3 years now and think it's great value for what you get.
