Item - 2026.PB44.1

The Toronto Preservation Board recommends that:

1. City Council include 8 Arnold Avenue on the City of Toronto's Heritage Register in accordance with the Listing Statement (Reasons for Inclusion) attached as Attachment 1 to the report (April 27, 2026) from the Senior Manager, Heritage Planning, Urban Design, City Planning.

This report recommends that City Council include 8 Arnold Avenue on the City of Toronto's Heritage Register for its cultural heritage value and interest according to the Listing Statement (Reasons for Inclusion) found in Attachment 1.

The subject property at 8 Arnold Avenue is located just within the northern boundary of the Rockcliffe-Smythe neighbourhood, south of Lambton Avenue, in the Mount Dennis area. The residence is notable as a red-brick, one-and-one-half-storey Ontario Farmhouse-style property, dating to the c. 1870s – 1880s, and historically known as the George Marshall Residence. The property, which is the earliest known house in the community, serves to recall the community’s former farming and settlement past. A location map and current photograph of the heritage property are found in Attachment 1.

The property recommended for inclusion on the City’s Heritage Register has been researched and evaluated by staff using the criteria prescribed in Ontario Regulation 9/06 and meets one or more of the provincial criteria for determining cultural heritage value or interest and is believed to be of cultural heritage value or interest.

In 2021 the subject property was identified for its potential heritage value in the Mount Dennis Cultural Heritage Resource Assessment (CHRA), which was completed as part of the Picture Mount Dennis Planning Framework Study. The Mount Dennis Secondary Plan Final Report, which was adopted by Council in July 2022, stated that properties identified as having potential heritage value through the CHRA would be reviewed for inclusion on the Heritage Register.

On January 1, 2023, amendments to the Ontario Heritage Act (the Act) through the More Homes Built Faster Act, 2022 (Bill 23) came into effect. Under the Act, as amended, a municipal heritage register may include properties that have not been designated but Council believes to be of “cultural heritage value or interest", and that meet one or more of the provincial criteria for determining whether they are of cultural heritage value or interest. The Act now also limits listing to a period of two years.

As of January 1, 2023, should a property be subject to an Official Plan Amendment, Zoning By-law Amendment and/or Draft Plan of Subdivision Application, properties must be listed on the heritage register prior to Part IV designation and before the occurrence of a prescribed event. A prescribed event is a point of time when the application for an Official Plan Amendment, Zoning By-law Amendment and/or Draft Plan of Subdivision Application has been deemed complete and the City Clerk provides notice of that complete application to the public in accordance with the Planning Act. 

The listing of non-designated properties on the municipal heritage register under the Act also extends interim protection from demolition and provides an opportunity for City Council to determine whether the property warrants conservation through designation under the Act should a development or demolition application be submitted.

Properties on the Heritage Register will be conserved and maintained in accordance with the Official Plan Heritage Policies. Heritage Impact Assessments (HIA) are required for development applications that affect listed properties.
