Tower Renewal Summit 1 - April 27, 2009

This summit is the first of a series of luncheons that focus on the critical importance and value of re-skinning commercial office buildings to save energy and enhance cities.

His Worship David Miller, Mayor of Toronto, has launched a new campaign on Tower Renewal and will join us on April 27 as he presents this campaign in Alberta. Described by the Globe and Mail as “the most exciting initiative to emerge in a generation.” This is a great opportunity to learn more about how we can reimagine the future of Alberta’s office towers.


David Miller was a partner at Toronto law firm Aird & Berlis before becoming a Metro councillor in 1994. In 1997 he was elected to the new City of Toronto council where he served two terms.

Torontonians chose David Miller as their new mayor in November 2003. He was re-elected in November 2006 with a mandate to make Toronto a city of prosperity, livability and opportunity for all.

Among his proudest accomplishments is securing a New Deal for Cities. This has enabled Toronto to get new powers, money, and respect from the provincial and federal governments. Mayor Miller has also become a vocal champion for the national urban agenda.

As Toronto’s government matures, the City is reinvesting in its neighbourhoods with initiatives like the Mayor’s Community Safety Plan, the Clean and Beautiful City program,waterfront revitalization and the Mayor’s Tower Renewal project. This is leading to real change that has inspired a new sense of civic pride and, responsibility among Torontonians.

Mayor David Miller’s role in leading the Toronto’s environmental agenda was recognized by the influential C40 Group which last year appointed him as its Chair. The C40 Group’s membership includes such major world cities as Athens, Berlin, Chicago, Hong Kong, London, Los Angeles, New York, Sao Paulo, Seoul and Tokyo. The organization was set up in London in 2005 with the aim to accelerate cities’ programs to combat climate change.

Mayor Miller and his wife, lawyer Jill Arthur, are the parents of two children
