As Netflix is a major purchaser of independent productions and contracts out the production of a number of it's own properties, they have camera standards, similar to other networks like BBC, Discovery, natGeo, etc. Because it's become such a behemoth in the industry, it's camera specs are watched by all the manufacturers.
Netflix made some waves in the DP community a few years ago when it required 4k capture, essentially blacklisting the most popular camera in the single camera series category -- Arri's Alexa XT. While this camera is responsible for some of the best digitally-captured large screen productions and a huge percentage of TV series produced world wide, it only captures 3.2k and thus is not allowed by Netflix's standards to be used as an A camera. It's stupid, really, most experienced DP's will tell you, but Netflix has stuck to it's guns...essentially forcing Arri to create a 4k camera (the 65 and later the LF) that could be used on Netflix shows.
Now to Canon...not really a big deal, as all of it's Cinema EOS cameras except the C100mkII and C200 are Netflix certified, including the original C500. Not sure why the C200 is excluded...but it's currently not on their list.
(edit: apparently the C200 isn't officially certified by Netflix because it cannot accept timecode input, which would be important if it was being used with other camera's on a set. Thus while not officially certified the C200 can be used in RAW mode on a case by case basis).
