Hey Reinvestiors88,
I'm a realtor specializing with investors in KWC and the majority of my single family clients go with KW Property. They're amazing!
Their website is - http://www.kwproperty.com/ - Let them know I sent you
If the property is a student rental or is in Waterloo specifically, go with Adam Hoffman! His website is - http://www.hoffaco.com/ - He's the smartest man I know when it comes to tenants, LTB etc.
