Well the good (bad?) thing about the CF is that there is a publication for everything. Chapter 11 in The Heritage Structure of the Canadian Forces publication (the 200) details forms of address for CF members. I've included the parts most people will probably find useful. The table in the attached Annex A of the chapter will probably be most clear:
CHAPTER 11
MILITARY FORMS OF ADDRESS
GENERAL POLICY
1. This chapter:
a. amplifies the National Defence Act, Section 21, and Queen's Regulations and Orders (QR&O), Article 3.01;
b. prescribes the correct forms of address for members of the Canadian Forces (CF) and establishes the standard for use by CF members, but
c. does not preclude the local use of terms or titles based on traditional establishment appointments, e.g., gunner, sergeant-major.
2. In general, CF members may be addressed by either:
a. Rank and surname;
b. Rank;
c. Appointment (including parade appointments);
FORMAL ADDRESS
9. In formal address, either written or spoken, the correct form of address shall be as follows:
a. Officers shall be addressed –
(1) by officers of higher or equal rank, by rank and surname, or by appointment;
(2) on parade, or when in keeping with authorized environmental or branch usage –
(a) by officers of higher rank or higher parade appointment, by rank and surname, or by appointment; and
(b) by officers of equal rank but lower parade appointment by Sir or Ma’am as applicable; and
(3) by all other officers and noncommissioned members, by rank and surname, or by Sir or Ma’am as applicable.
b. Chief Petty Officers 1st Class and Chief Warrant Officers shall be addressed by all ranks –
(1) by rank, by rank and surname, or by appointment; or
(2) for army and air force chief warrant officers –

(b) by lower ranks, by Sir or Ma’am as appropriate.
c. Other non-commissioned members shall be addressed – by all ranks, by rank, by rank and surname, or by appointment.
INFORMAL ADDRESS
10. Normally, short forms of address (see Annex A) are limited to informal speech and in the salutation of informal correspondence.
11. Nothing in this order prohibits the continued use of given names in a social setting within the bounds of normal etiquette and traditional military discipline.
