Markham’s Mount Joy neighbourhood is on the verge of a major transformation with a proposal for three high-rise towers near the Mount Joy GO Station. Developed by Sunny Communities in partnership with Cham Shan Temple and designed by Wallman Architects, the project aims to replace an existing one-storey commercial plaza and place of worship at 9441 Markham Road. With a total of 1,218 condominium units, retail space, and a new public park, the development seeks to integrate seamlessly into the growing Mount Joy Major Transit Station Area, part of northern Greater Toronto’s transit-oriented development plan.
Project Overview
The 14,577 m² site sits east of Markham Road, about 200 metres south of Bur Oak Avenue. Currently occupied by retail spaces and a temple, the rectangular property is surrounded by a car dealership to the south, emerging towers across the street, and low-rise housing to the east along the Stouffville rail corridor.
The proposed plan includes:
- South Block: One 30-storey tower (104.6m) with 341 units, 254m² retail, and a four-storey podium.
- North Block: Two 35-storey towers (123.2m) containing 877 units, approximately 1,850m² retail, and 1,852m² dedicated temple space across the third to fifth floors.
- Amenity Space: 2,192m² indoor and 2,192m² outdoor spaces on the fifth floor, with podium terraces for residents.
- Public Park: 0.15 ha block designed to expand local open space and frame a new internal east-west street.
The towers will maintain a minimum 25m separation between tower faces, and a 28m rail buffer with crash wall will separate the development from the Stouffville rail corridor.
Residential and Parking Details
The development will focus on one- and two-bedroom units, offering 819 one-bedroom and 399 two-bedroom suites, with no studios or three-bedroom options. Two levels of underground parking will accommodate 453 vehicles, including residential, visitor, and institutional spaces. Bicycle parking will total 1,167 spaces, supporting the city’s active transportation goals.
This combination of residential density, amenity-rich podiums, and sustainable transport options highlights a clear transit-oriented development strategy near Mount Joy GO Station, encouraging residents to adopt transit and active mobility.
Transportation and Connectivity
Mount Joy GO Station is only 500 metres from the site, or a seven-minute walk, connecting residents to the Stouffville Line and broader GO Transit network. Surface transit options include TTC and York Region Transit buses, while cyclists benefit from dedicated bike lanes on Castlemore Avenue and shared pathways along Markham Road. The proximity to multiple transit modes reinforces the site’s role as a key transit-oriented neighbourhood in Markham.
Neighbourhood Development Context
This proposal is part of broader growth around Mount Joy GO Station. Nearby projects include:
- Platform 68: Towers rising 37 and 42 storeys south of the station.
- Joy Station: Two 22-storey towers currently under construction.
- Station Town and Joy Station Phase 2: Mid-rise developments at 18–33 storeys.
- 77 Anderson Avenue: 42-storey tower proposed further north.
The area is rapidly evolving, combining residential, retail, and institutional uses to create a vibrant, transit-connected community.

Implications for Markham
The Mount Joy GO towers project will significantly increase residential density in northern Markham while providing public park space and improved pedestrian and cycling infrastructure. With its proximity to transit, the development supports the city’s sustainable growth and intensification goals. For developers, this project represents an opportunity to contribute to a fast-growing, well-connected urban corridor while balancing community amenities and transit-oriented design.
Conclusion
Sunny Communities’ Mount Joy GO towers proposal represents a transformative transit-oriented development in Markham, bringing over 1,200 new homes, retail frontage, and public green space to a key transit hub. As construction momentum builds in the Mount Joy neighbourhood, this project underscores the city’s push toward high-density, sustainable, and amenity-rich urban growth in alignment with regional transit and housing objectives.
