In Ontario, the permissions and regulatory authorizations that determine what can be built on a given piece of land take the form of approvals: Official Plan Amendments, Zoning By-law Amendments, Plans of Subdivision, Site Plan Approvals, Conservation Authority Permits, and the layered municipal and provincial processes that govern development across the province. These are the entitlements that every development project must secure before construction can proceed.
Navigating this approvals landscape is one of the most consequential and time-sensitive aspects of any development project. Through more than 9,000 projects across Ontario, Crozier has cultivated deep relationships with Canada’s most respected planning and architecture firms, environmental consultants, and legal advisors. We connect the right specialists to every file and coordinate their contributions alongside our engineering teams to advance your project through the approvals process with clarity and confidence.
The following is a comprehensive reference of the approvals, permits, and authorizations that Crozier routinely facilitates and supports across our market sectors. If you are unsure which approvals apply to your project or what technical materials will be required, contact us and we will map the path forward.
Crozier prepares the engineering inputs and supporting technical documentation required to advance planning and development applications at the municipal, regional, provincial, and federal levels, and before tribunals when applications are contested.

Not every contested file reaches a hearing room — and that is often because Crozier’s technical expertise helped resolve it first. When applications are appealed or disputed, Crozier supports the full continuum: from pre-hearing conferences and case management through public meetings, mediation, and formal tribunal proceedings. Our engineers prepare and present defensible technical evidence, support legal counsel, and respond to cross-examination before the Ontario Land Tribunal (OLT), Toronto Local Appeal Body (TLAB), Building Code Commission (BCC), Mining & Lands Tribunal (MLT), and Ontario Superior Court of Justice (OSCJ). Where files are resolved through mediation, Crozier’s ability to find technical common ground on servicing, transportation, and engineering matters is frequently what makes minutes of settlement possible.
Pre-Hearing Conferences & Case Management Support — technical preparation and representation at pre-hearing conferences where issues are defined, technical positions are established, and timelines are set before formal proceedings begin.
Public Meeting & Statutory Hearing Preparation — preparation of technical materials, presentations, and responses for statutory public meetings before municipal councils and committees where planning applications are presented and debated.
Mediation Support & Minutes of Settlement — technical support through mediation processes where contested planning and engineering issues are negotiated, with Crozier’s engineers frequently central to achieving minutes of settlement that avoid full tribunal hearings.
Tribunal & Formal Hearing Testimony (OLT, TLAB, BCC, MLT, OSCJ) — expert engineering testimony, evidence packages, and representation at formal tribunal and court proceedings, where Crozier’s engineers present and defend technical findings under cross-examination.
