The MaRS Innovation District in Downtown Toronto is one of the oldest high technology clusters with the exception of Silicon Valley in the US.
MaRS is also one of the largest and highest concentrated clusters with many small to medium-sized businesses. In common with the clusters we have visited In Cambridge/Boston US, they are focused on generating social impact as much as wealth. They say they bring together "educators, researchers, social scientists, entrepreneurs and business experts under one roof”. I visited other innovation centres and co-working spaces, but MaRS certainly was one of the most ‘corporate’ looking with it’s sleek glass-sided high rise towers.
