In fact, the code applies to all the MPs, including the Prime Minister and ministers. It contains obligations that are similar to those contained in the act, but many of the obligations in the act do not apply to private members.
The only members the act applies to are ministers or parliamentary secretaries. There are several additional obligations, but I would have a hard time listing them. I brought the table of contents of the act. Many aspects that were not regulated in the code are regulated once the individual is appointed as a minister or parliamentary secretary.
However, the question you are asking me is very complex. It would take a seven- or eight-page comparative table to try to answer it.
