Sure. I will turn to Begonia in a second to assist me in this answer, but I'll give you the knowledge I have to start.
One area in which we have used consultants for some time is auditing. We employ auditors to help us deliver our ISO 9000 and ISO 14000 certification programs.
I was there about 15 or 20 years ago when we did an analysis when we began this program in CGSB. I'll be very frank with you: there has been continuous progress in CGSB to ensure that it is not working in a domain where the private sector should deliver services. So while we recognize the important role we play in the public sector, we also seek to ensure that, where we can, we utilize resources in the private sector, especially because they can be far more cost-effective.
For example, we carry out a series of audits for clients all across Canada, and we have them in the United States and even in other countries. It's far more cost-effective for us to contract with consultants who have the technical expertise, the skills, and the knowledge. We don't then have to employ them on a continual basis. It has been a more cost-effective model for us.
Begonia, would you like to add anything?
