Have you checked with Exp., they are the old TROW group. They may have branches in Quebec, but, they had a Toronto office and likely still do. They used to be an extremely good group and I had used them often.

Dik

disclosure.....I am not affiliated with exp; however, I was once a partner with The Trow Group, their predecessor and know their reputation and capability. dik's assessment is correct, in my opinion.

Thanks, Ron... At the time of my involvement with them, they were the best testing agency I had ever encountered

dik...I was a partner with Trow from 1983 to 1989 and was their US affiliate. They have always been a topnotch organization.
