A Canadian investor group operating as Royalton Condominium LP purchased the Royalton at River Oaks in March 2007. The Managing General Partner of the investor group is Group LSR, a Montreal-based real estate development company that has acquired, managed and developed over $400 million in single and multi-family projects in the United States, Canada and Europe. Current Group LSR projects include a 1,000 unit master-planned community in Laval, Quebec, and a new development in Warsaw, Poland. Additionally, a new health division is developing senior living centers and medical clinics in Quebec, Canada.

Group LSR's USA Apartment Division, LSR Management Inc., has owned and operated apartment communities in Houston since 1989. With the purchase of four apartment properties in 2006 and early 2007, the company now operates 13 communities in the Houston area.

In 2004, Group LSR created innerLoopCondos.com, a condominium development company that has since built two mid-rise projects: The Vistas at Midtown, and Piedmont at River Oaks. A third mid-rise project, Serento Condominium, is under construction with an expected completion in mid 2008.
