Mainstream To improve quality of life for people with a developmental difference

The Goal of Mainstream is: "That all people are able to develop their full potential as individuals with respect and dignity, enjoy integration in the community and have the opportunity to prepare for the future." This goal challenges the community to have each of its citizens experience equality, individuality and social role valorization. The dignity and selfrespect that people enjoy in their ow

n communities are a result of a supportive environment that fosters personal growth, self-reliance and acceptance. In working towards this goal, Mainstream will provide the necessary resources and supports to ensure that individuals who have a developmental challenge:

• have the opportunity to lead full and productive lives and have the ability to recognize and reach their potential in the competitive work place

• are made aware of services and programs available to them in the community

• have access to affordable housing

• be valued contributors in the community with due recognition of their accomplishments

Recognizing that our daily experience goes hand-in-hand with our quality of life, our aim is to provide the necessary tools that will enable each individual to:

• exercise self direction and ownership of choices

• develop academic, vocational, life and social skills and realize their full potential

• deal with real life situations effectively

• enjoy friendships and other supportive relationships

• exercise their rights and responsibilities

In conclusion, Mainstream is all about people supporting people. It upholds the ideas of mutual respect, the value of individuality and openmindedness toward the ever changing needs of its people.

A little holiday magic with a big impact ✨

Shelly from Photography by Shelly has been such a gift to our community. She has spent time with us capturing the heart of who we are—our people, our stories, and the work we feel so privileged to do. Her photos have become a beautiful reflection of the compassion and connection that define Mainstream and Gateway.

This year, Shelly is offering Holiday Mini Sessions, and she’s chosen to turn them into something even more meaningful. For every session booked, she is generously donating $25 directly to Gateway Niagara and Mainstream.

It’s a simple way to get gorgeous family photos while also supporting the individuals and families we serve every day.

If you’re looking to add a touch of holiday joy to your year—and help us continue our mission—we’d love for you to check out her sessions.

📸 Holiday Minis
• 20-minute session
• 15 beautifully edited images
• $225 + HST
• $25 donated to Mainstream & Gateway

Thank you, Shelly, for using your talent to lift up our community. And thank you to everyone who books a session—you’re helping create brighter futures.

This is such a vital initiative. Sign the petition to help thousands of individuals receive the support.

This is such a vital initiative. Sign the petition to help thousands of individuals receive the support.

More than 53,000 adults with intellectual disabilities in Ontario are still waiting for vital services. Decades of delay have left too many at risk of homelessness, human trafficking, criminal exploitation, and extreme poverty.

This cannot continue. Sign the petition today at Waiting2Belong.ca to help spread the word.

A very impactful message to hear
