Read the reviews of some of our clients.
Extremely professional. I was very impressed. We have used other firms, but no one was as professional or as thorough as these people. Can't thank you enough.


The best decision I have made to hire Discreet Investigations, from the first phone call I made when I spoke with James I felt I was in good hands, The whole team worked in a very professional manner and got us the result we were looking for. Thanks James we could not have got what we got and saved our company if we haven't met you.


As a US citizen, I needed the services of a Private Investigator in Canada to locate an individual and collect a debt. After much research, I found James Glanville and Discreet Investigations. I could not be more satisfied with this choice and the services provided. Within a very short period of time, the culprit was located, and a satisfactory result was achieved.
