Seaton Group
A small, diversified family-owned group of businesses.

Specialty Real Estate Development
The common theme of the Grant family's investments is land: developing it to its most appropriate, highest and best use. Whether it's restoring and re-purposing a historic building, creating a residential community on urban-designated farmland, investing in a company that cleans up land and water, or utilizing a piece of Belizean jungle - we seek to recognize and enhance the value of our natural and built heritage, and compliment it with thoughtful design and excellent architecture.

Seaton Group was founded by Jack Grant in the 1950s. Grant engaged architect Jerome Markson to design his early mid-century modern projects in Elliot Lake and Seneca heights in Woodbridge. Markson is now recognized as a Canadian architectural pioneer.

Grant had an affinity for smaller towns within commuting distance of Toronto. He chose towns that had charming main streets and rivers running through them, and built expansion that complimented and enhanced their unique charms.

Projects in the 1970s and 1980s included major expansions of the villages of Unionville, Woodbridge and Uxbridge. He never dreamt that the Toronto urban area would eventually engulf the former two.

Stewardship of the company was assumed by two of Jack's sons, Jeremy and Jordan in the 1990s. Major projects completed since the "boys" became involved include most of  the Woodbridge projects and Uxbridge. Thistlewood, Rockwood Ridge and subsequent projects were initiated by the second generation.

In addition to the land development projects, Jack always had outside interests in both the business and social justice realms. That legacy continues today, with the group's diversified investments in operating businesses that involve preserving, protecting and adding value to land and our built heritage.

With provincial policy now encouraging intensification most of the company's newer developments are smaller infill projects rather than large-scale greenfields developments.

A professional planner, Jeremy's focus remains on development, whereas Jordan takes responsibility for the operating businesses. Both are deeply involved in the Alton Mill Arts Centre, by passion, not design.

Completed Projects
Here is a sampling of a few projects completed in the past.
Rockwood Ridge

Rockwood ridge was a 480-unit multi-phase expansion of the quaint village of Rockwood, Ontario. It maintained the small-town feel through houses with porches rather than garages dominating the streetscapes. Natural open spaces (including a forested ridge) were preserved, made visible  from the streets and interconnected with walking trails. A variety of housing types were built from large bungalow and two-storey single detached home to a range of townhome designs.

Market Lane Shopping Centre
Market Lane was  an award-winning infill project that revitalized the historic commercial area of Woodbridge. It included the restoration and adaptive reuse of several heritage buildings and construction of new, historically-inspired buildings around a newly-created village square. 
Thistlewood Professional Centre
Thistlewood was built to house a variety of  medical services, a pharmacy and restaurant on Islington Avenue in Woodbridge.
Downey Trail
Downey Trail was a 45-unit infill site in Southwest Guelph. It won the support of the neighbouring single family residents by restoring a historic farmhouse, inserting tastefully-designed townhomes (including some bungalow-with-lofts), and 16 units in an innovative four-plex design utilizing the slope overlooking an open space area.
Quaker Village
Multi-phase westerly expansion of Uxbridge, featuring victorian architecture with front porches, side garages, and a huge central park.
Arbors Condominiums
Mid-rise building plus hillside terrace units in Woodbridge.
