Strategic Storage Trust VI, Inc. Announces Opening of New Self-Storage Facility in Toronto, Ontario

LADERA RANCH, Calif. – June 3, 2025 – Strategic Storage Trust VI, Inc. (“SST VI”), a publicly registered non-traded real estate investment trust sponsored by an affiliate of SmartStop Self Storage REIT, Inc. (“SmartStop”) (NYSE: SMA), in partnership with SmartCentres (TSX: SRU.UN), is

proud to announce the opening of its 14th facility in Canada and its 12th in the Greater Toronto Area, located at 1480 Jane Street in Toronto.

This six-story, climate-controlled facility spans approximately 105,000 net rentable square feet and includes more than 1,200 climate-controlled storage units. Strategically positioned on a 2.67-acre site, the property offers strong visibility along Jane Street, which averages more than 40,000 vehicles daily. The location is equipped with two elevators and sits south of a recently opened FreshCo grocery store and within the heart of Toronto’s Mount Dennis, Brookhaven and Weston neighborhoods.

The new facility is well positioned to serve a densely populated and growing urban area. Within a three-mile radius, demand for convenient, secure storage is rising – driven in part by development plans that call for 2,000 new residential units within five miles of the site.

SmartStop's newest location will serve the surrounding communities of Maple Leaf, Rockcliffe–Smythe, Richview, Brookhaven–Amesbury, Beechborough–Greenbrook, Glen Park, York and Humber Heights–Westmount.

“Toronto continues to be a key market for us, and this new Jane Street facility strengthens our presence in one of its fastest-growing areas,” said H. Michael Schwartz, Chairman and CEO of SST VI. “We’re committed to meeting the needs of the surrounding communities with secure, high-quality storage, and this location is a great example of how we’re delivering on that promise.”
