SmartStop Self Storage REIT, Inc. ("SmartStop") (NYSE: SMA), an internally managed real estate investment trust and a premier owner and operator of self-storage facilities in the United States and Canada, announced that an additional self-storage facility has been contracted for third-party management services, the Company's first in Canada, further expanding the company’s growing management platform across North America.

The newly contracted facility is an approximately 80,910-square-foot property in Aurora, Ontario, Canada, comprising 829 units. The Aurora facility strengthens SmartStop's presence in the Greater Toronto Area, one of North America's fastest-growing metropolitan markets, where SmartStop and its affiliates already own or manage a substantial portfolio of operating properties.

"This agreement represents something we never take for granted: owners trusting us to maximize their investment," said H. Michael Schwartz, Chairman and Chief Executive Officer of SmartStop. "When an independent owner hands us the keys, they are counting on sophisticated revenue management, marketing that drives qualified demand, and the operational expertise that comes from a team that lives and breathes self-storage every day. As the largest self-storage operator in the Greater Toronto Area, our platform is built to deliver measurable performance for the people who built these businesses."

SmartStop's third-party management platform is purpose-built for self-storage entrepreneurs, offering three flexible management models, access to the company's proprietary technology platform, revenue management expertise, integrated marketing, and a fully staffed operations team of more than 1,000 self-storage professionals.
