One of the best networking opportunities in the Ottawa area is something that is known as Tech Tuesday and is sponsored by Terry Matthews. It is held on the first Tuesday of every month at the Marshes golf club and is open to the public. I have never seen a mission statement for the event but the people who attend range from entrepreneurs looking for money, to recent college grads looking for jobs. The focus is very much on information technology and how it can create wealth for Canadians.
There is no charge for attendance except for drinks at the bar. However, organizations like accounting and legal firms tend to serve some finger food for those who might feel the pangs of hunger before the event winds down.(It starts at 5:30 pm and ends about two or three hours later, depending on whether or not there is a formal presentation of some kind.)
