The Greater Toronto and Hamilton area (GTAH) Caucus of RPCO comprises members from:
- Durham Region
- Halton Region
City of Hamilton
- Region of Peel
City of Toronto
- York Region
The Caucus's philosophy is that a co-ordinated approach to regional planning is beneficial given that GTAH regions share similar challenges, values and are all part of the same economic region. Increasing population growth demands for infrastructure, transportation and human services, in combination with increasing levels of municipal responsibility, underscore the need for a higher degree of planning co-ordination among the GTAH regions.
The GTAH Caucus has examined Growth Management issues as they impact the GTAH. The GTAH Caucus has developed a Centres and Corridors report.
The GTAH Caucus has developed a GTAH Agricultural Action Plan. A GTA Agricultural Action Committee was formed, and a job posting for the Agricultural Action Committee Executive Director was posted in November 2005. In March 2009, a GTAH Demographic Profile was released. The Profile provides the agricultural industry with information to assist in identifying GTAH markets and their geographic location through population, immigration and economic Census data.
The Chair of the GTAH Caucus is Brian Bridgeman.
