Mainstream Building
We are here to make a difference!
Welcome to the website for St. Catharines Mainstream Non Profit Housing and Mainstream: An Unsheltered Workshop.  Together the two charitable non profit corporations operate as Mainstream with a shared board of directors and senior management.  We have provided progressive residential and day support services for adults with a development disability since 1984.

Today we are a fully accredited organization committed to building partnerships to create opportunities for the people we support , our volunteers and our employees to make the community a better place for all citizens.  Please have a look to see how we make a difference!!
