Looked at a tech event calendar I have - saw this: http://www.ice08.com/

Their website is not up to date yet, but you can see what last year's was like at http://www.ice07.com.

Also had a co-worker in our Toronto office a few years back that participated in some future leaders networking group. Not sure if it was this? Looks like the same type of events, though the last event posted is a year old - so not sure how active they still are.

And making an assumption here based on your FF name (Emma) -- met some folks in my travels that run this fitness studio. Also met some of the women who work out there - was really surprised in terms of the career mix - a majority were business professionals or running their own companies. All very fun people (and have met up with a few in Chicago since then). So just throwing it out there (and apologies in advance if you are male or it is not age appropriate!).
