Our impact
Supporting the most vulnerable people at every step of their journey
For over 30 years, Plein Milieu has been a front-line organization working with people who use drugs and people experiencing or at risk of homelessness in the Plateau-Mont-Royal. We also offer prevention and support services to young people aged 12 and up.
In schools, on the street and at our drop-in centre, our team supports the most vulnerable people at every step of their journey: preventing risky behaviours starting in high school, intervening when substance use, homelessness or other vulnerable situations arise, and then helping people move toward greater housing, social and personal stability.

Rising risks, stretched resources
Yet just as needs are skyrocketing, community organizations are coping with limited resources and funding that struggles to keep up with demand.
+20% more people experiencing homelessness in Quebec between 2022 and 2025.
900+ overdose-related field interventions since the start of 2026.
+1,000% increase in sexually transmitted infections in Canada over 25 years (on average).
The people Plein Milieu supports face situations that greatly increase the risks to their health and safety: psychoactive substance use, homelessness, poverty, isolation, violence and unprotected sex. And these realities are on the rise.
Our solution: Prevent. Intervene. Support.
Poverty, isolation, family difficulties and psychological distress can increase the risk of substance use, homelessness and exposure to sexually transmitted and blood-borne infections (STBBIs).
At every step, Plein Milieu offers support that changes lives:
Anticipating and preventing risky behaviours
Nearly 3,000 one-on-one interventions with youth and 300+ workshops delivered in the past year.
We’re present in 3 Montreal high schools to act early: raising awareness, educating and answering young people’s questions before vulnerability takes hold.
What we do:
- Workshops on sexuality, STBBI prevention and awareness of psychoactive substance use;
- One-on-one support for youth facing personal, family or school difficulties;
- Sport-based intervention programs, such as Elle-O-Sport and boxing, that build self-esteem, healthy habits and empowerment.
Supporting people and helping them make decisions
Nearly 15,000 interventions with youth and adults in 2025-2026.
Through street outreach and our drop-in site, Plein Milieu keeps a close presence in the community. This lets us support people and help them access resources.
What we do:
- Street outreach: a presence on the streets and in public spaces to build trust and offer support.
- Drop-in site: distribution of prevention supplies, information and support at each person’s own pace.
- Street messengers: peer helpers who reach the most marginalized people through their own lived experience.
- Social mediation: support for housed and unhoused people to help everyone share the neighbourhood.
- L’Oranger: a network of solidarity businesses giving people experiencing homelessness access to essential services.
Building stability and better living conditions
40 people supported into housing in 2025-2026.
Beyond emergencies, Plein Milieu supports people who want to improve their living conditions and regain control over their lives.
