About Us


Regroupement pour la Trisomie 21 (RT21) is a registered charity based in Montreal, but serving hundreds of families in the province of Quebec. Its mission is to foster the full development of people with trisomy 21, promote their contribution in the society and defend their rights in addition of helping the families, caregivers and professionals who support them.

Services and activities

We offer many services and activities to our members such as access to specialized services (occupational therapy, speech therapy, physiotherapy) for the families waiting for public services, language stimulation program, conferences, parents meetings, recreational activities and parental support. To reach families as soon as the birth of their child, we distribute a New parent package in all CLSCs, hospitals and birth centers. We also have a day program for young adults to help them develop autonomy by using technology.

Awareness and advocacy

It’s important for RT21 to organize many awareness activities in addition of disseminating the most information possible to the public so we can reduce stereotypes and prejudices towards people with Down syndrome. Each year, the team and members of RT21 meets with many community workers and healthcare professionals to explain what is trisomy 21. We also do many interviews in various media.
