TEMPLATE Letter for Members to Use to Submit Responses to ERO Posting on Growth Plan February 13, 2019
The government has submitted a proposal to make Modifications to O. Reg. 311/06 (Transitional Matters - Growth Plans) made under the Places to Grow Act, 2005 to implement the Proposed Amendment to the Growth Plan for the Greater Golden Horseshoe, 2017. OSSGA has made the point to the government that the current policy framework is not working. Approvals for new mineral aggregate operations in Southern Ontario are taking up to 10 years to complete the process. There are too many overlapping policies and inconsistent approaches between the Provincial Plans, Regional Official Plans, Local Official Plans and Conservation Authority policies regarding the management of this essential non-renewable resource.

OSSGA Releases Environmental Legal Register

May 24, 2017 at 1:27 PM

OSSGA has developed an environmental legal register to help our members maintain compliance with federal and provincial environmental legal requirements (legislation, regulations, standards and guidelines) that impact the operation of pits and quarries in Ontario. The register is an excel table and contains headings with appropriate filters so you can easily search for the categories (e.g.  water taking, endangered species, air and noise) applicable to your operations. The register also contains a high-level description of additional legislative requirements (i.e. permitting and planning) related to environmental aspects.

This environmental legal register complements OSSGA’s Environmental Management Guide for Pits and Quarries and Best Management Practices (developed in 2016) to help you accomplish your site specific environmental goals, programs and procedures.

The register will also be available in the Members Area of our website. If you have any questions regarding the legal register, please contact Ashlee Zelek at If you have any questions regarding access to the Members Section, please contact Eva DaSilva at
Please note that the information contained in this legal register is intended as general information only and is not intended to serve as a replacement for professional or legal advice. Although every effort has been made to ensure accuracy and completeness, OSSGA is not responsible for the results of any actions taken on the basis of the information collected in this register, or interpretation of the legislation and regulations applicable to your operations. The register is current as of the date referenced; OSSGA will provide updates to this register annually.
