Continuing commitment to affordable housing by adding 97 new community housing units
Newmarket – On Monday, October 27, 2025, The Regional Municipality of York and Housing York Inc. proudly hosted the grand opening of Mosaic House, a new community housing building in the Town of Whitchurch-Stouffville.
Located at 5676 Main Street, Mosaic House offers 97 residential units, including a mix of affordable and market rent homes for seniors, families and individuals. Mosaic House opened its doors to its first residents in March 2025 and was fully occupied by June 2025. This building features an indoor amenity space, rooftop patio and parking, creating a welcoming and inclusive environment.
“Creating safe and secure housing where residents can thrive takes a collective effort and we appreciate the federal and provincial governments for their financial support,” said York Region Chairman and CEO Eric Jolliffe. “Affordable housing is one of the greatest challenges facing York Region today and we remain committed to supporting communities with a full range of housing options and services to support all residents.”
The $50.96 million investment for Mosaic House and additional lands for a future phase was made possible through strong collaborative partnerships across all levels of government, including $18.9 million from York Region and nearly $18.9 million and $11 million from the Federal and Provincial governments, respectively.
“The federal government is committed to providing communities the support they need to develop local solutions to homelessness. Access to adequate, affordable housing is the foundation for socio-economic success. The official opening of Mosaic House is another example of the federal government’s commitment toward ensuring that no one is left behind. Thank you to all our partners and people behind the scenes who helped bring this project to completion”. – The Honourable Gregor Robertson, Minister of Housing and Infrastructure and Minister responsible for Pacific Economic Development Canada
“The official opening of Mosaic House will make a real difference for people here in Whitchurch-Stouffville and ensure that everyone, especially the most vulnerable, has access to a safe and stable home. This project is a vital step toward providing affordable housing for those who need it most. It highlights the power of collaboration, and it's yet another key step in our bold, forward-thinking plan to build a stronger and more resilient Canada.” – The Honourable Helena Jaczek, Member of Parliament for Markham—Stouffville
“The grand opening of Mosaic House shows how our government is taking action to expand access to affordable housing across Ontario. By investing in innovative housing solutions and working closely with municipalities and community partners, we’re helping ensure more individuals and families have a safe, stable place to call home, right here in Whitchurch-Stouffville and across the region.” – Graydon Smith, Associate Minister of Municipal Affairs and Housing
“We are seeing growing demand for affordable housing across the Region,” said Town of Newmarket Mayor John Taylor, Chair of Housing York Inc. “Mosaic House is a great step forward, but we must continue to work together to build more in order to meet the needs of our residents.”
“The opening of Mosaic House is a positive step forward in our commitment to having housing options for all residents,” said Town of Whitchurch-Stouffville Mayor Iain Lovatt, Vice Chair of Housing York Inc. “This is another example of how all levels of government can come together with shared purpose and coordinated action to support our communities and create affordable housing options.”
In February 2021, York Regional Council declared a housing affordability crisis and continues to work with partners and all levels of government to find solutions and provide a full range of housing options to meet resident needs of all ages, abilities, income levels and stages of life.
All levels of government play a critical role in supporting communities with affordable housing. A shared funding model, where each level of government contributes one-third, would enable the Region to nearly double the growth rate of the past 10 years.
