Moving back to Ottawa: who are some reputable temp agencies for professional office work?

Hi, I'm looking to move back to Ottawa for better job opportunities (Currently near Lindsay.) I'm currently in job search mode here in Lindsay, but there's not too much available. I lived in Ottawa about a decade ago and unfortunately most of my network has moved on.

I was wondering if anyone had some positive experiences with temp agencies for professional work?

I've done Career Counselling, HR (L&D, Global HR, etc.) Any advice would be appreciated. :)
