In Ontario, a developer may need an Encroachment Permit and/or a Building and Land Use Permit for any project located along or near a provincial highway. The Ontario Ministry of Transportation (MTO) regulates the ability of any person or corporation “to use, or to construct, maintain and use buildings, structures or improvements in or on, any space or area located over, across, or under a highway under the jurisdiction of the Ministry” through the issuance of permits. R.S.O. 1990, c. P.50, s. 2(3).


MTO regulates provincial highway access and rights-of-way pursuant to Ontario – Public Transportation and Highway Improvement Act, R.S.O. 1990, c. P.50.
