IA9

Internal Affairs, Unit 9 (IA9) is the premier professional standards and anti-corruption unit of the Lower Mainland Constabulary (LMC), and the largest of the Directorate of Internal Affairs' three active unites. Chief Superintendent Fiona Wilson has been the commanding officer of IA9 since 18 March 2018. The main IA9 offices are located on the sixth floor of Cambie Street Station in Vancouver. All officers and civilian personnel working in IA9 are required to have at least the bravo level of security clearance, the second-highest security clearance in the constabulary, as is the case with the two other units of Internal Affairs.

Despite being referred to as a unit, IA9 in fact resembles a large squad in size, consisting of up to 10 detectives and at least 25 non-detective support constables, in addition to its leading superintendent and chief superintendent and at least 20 civilian support staff. The unit headquarters can grow even denser when collaborating with units of the RCMP, BCPP, CSS and/or other municipal police forces. IA9's primary responsibilities are investigating any and all allegations of corruption and/or professional misconduct within the Lower Mainland Constabulary, with the only such investigations not handled by IA9 being those investigating IA9 itself, which are handled by the smaller Internal Affairs units IA4 and/or IA5.

The two smaller units within the Directorate of Internal Affairs, namely IA4 and IA5, are primarily responsible for operation of the CHIS (confidential informant) program (IA4) and the witness protection program (IA5).
