The Jewish Canon is all about the OT Bible. The Jews don't have a NT Canon. The Catholics have an NT Canon and an OT Canon. The Protestants adapt the Catholics' NT Canon but reject their OT Canon. The Protestants OT is in line with the Jewish Canon. There are other less authenticated canons around.
The Jewish Canon the Christians mean is the 22 book Pharisaic Canon used around Jesus' time. I don't know if there is a significant difference between that and the OT Bible used by today's Judaism.
