The Sterling Hall School
Dalton managed the renovation and expansion of two construction phases at The Sterling Hall School, including a new wing with modern, spacious classrooms, expanded resource spaces and gymnasium.

Dalton partnered with Appleby College—an independent day and boarding school located in Oakville, ON—to expand and renew its middle school facility: Barr Commons. The project included a build-out of a new middle school locker area and commons space, a renovation of Appleby’s Student Success Centre and the addition of a new 1,700 sq. ft. design tech lab—all strategic needs that were identified in the school’s 2014 master campus planning exercise.

Featured Projects
Dalton is currently leading the integrated team building a world-class companion animal and equine hospital in King City, Ontario. King Animal Hospital will offer emergency, surgical, rehabilitation and extensive diagnostic services across its 58,000-square-foot state-of-the-art facility.


We are currently transforming a sprawling 40,000-square-foot former private residence into the future home of St. Anne’s School (SAS) - a new independent school for girls in Aurora. To meet current building code, much of the existing building's construction required modifications including improving the structure, life safety, mechanical and electrical systems.
As Construction Manager, we led an integrated team to execute the build of their new 41,000-square-foot Main Lodge.
Lodge features include dining and lounge spaces, a kitchen, bar, lockers, fireplaces, reception, washrooms, administrative offices, maintenance areas,
and nursery and child care.





Dalton was selected to complete a dramatic rebuild of this iconic club after a crippling fire caused the west side of the building to collapse. The 35,000-square-foot reconstruction features first-class locker rooms, new and improved dining spaces, outdoor patio and game lounge.
