​​​​​​​A site plan shows both design and technical aspects of development proposals and ensures that the project contributes to an attractive streetscape, blends with the character of the neighbourhood, or local area, and meets Town and Region (if applicable) requirements.

Site Plan approvals are regulated by Section 41 of the Ontario Planning Act. The entire Town of Newmarket is designated, by Council, as a "Site Plan Control Area". Development of any kind may not be undertaken in the Town of Newmarket until the Town has reviewed and approved the plans.

This page outlines the site plan approval process at the Town of Newmarket.
