12 Episodes (9 aired)
From The Lost Media Wiki
In the August 13, 1993 issue of The Winnipeg Free Press, there is an article detailing the cancelling of CR6. In the article, they note "Nine weekly episodes actually got posted. Three more were written, but didn't get produced." So there was 9 full episodes posted, and 3 more that were either only script/dialogue or was shot and didn't make it through production.
