The Land Registry Office recommends that expropriating authorities submit expropriation plans to the Land Registry Office and wait for review and approval thereof before submitting certificates of approval to the approving authorities for signature. The signing of the certificate of approval by the relevant approving authority will then trigger the commencement of the three-month period under Section 9(1) of the Expropriations Act (Ontario). Surveyors and others should not physically come to the Land Registry Offices for pre-approval, inquiry or co-ordination purposes. For more information see the letter from the Director of Titles here.
