Housing First programs face a structural test as substance use care moves to the center
Housing First has long been used to end chronic homelessness, but its promise weakens when substance use health needs are treated as an add-on rather than a core clinical concern. A national pan-Canadian workshop brought that gap into focus by asking a practical question: what does it actually take to embed substance use health care inside Housing First programs without losing the model’s low-barrier, person-centered design?
The discussion drew 59 participants, including direct service providers, people with lived and living experience, healthcare professionals, community leaders, researchers, and policymakers. Their collective view was not that housing and substance use care should be merged in some abstract sense. It was that people with complex needs are already navigating both systems at once, often through fragmented pathways that force them to repeat their story, re-enter the same services, and absorb the consequences of disconnected care.
The workshop turned that reality into a set of operational priorities. Four barriers stood out: fragmented services, workforce challenges, restrictive policy and funding environments, and stigma. Each of those problems affects care at a different point in the pathway, but together they create a system that is slow, rigid, and poorly matched to the needs of people who are trying to stabilize both housing and health.
Fragmentation is driving missed opportunities at the bedside and on the street
When housing teams, harm reduction services, primary care, mental health care, and addiction treatment operate in separate lanes, the result is predictable. Clients are left to coordinate their own care across agencies that may not share records, philosophies, or even basic referral processes. In a population already coping with unstable housing, trauma exposure, polysubstance use, or psychiatric comorbidity, that burden can be enough to shut the door on treatment entirely.
The workshop identified strategic alignment and cross-sector collaboration as major opportunities. Those are administrative terms, but the clinical meaning is direct: the more closely housing supports are coordinated with health and social care, the less likely it is that a person will fall through a gap created by program boundaries rather than by medical need. A person-centered Housing First model cannot function well if a client’s substance use care is delayed until a separate intake is completed somewhere else.
One of the sharpest findings was the role of stigma. Stigma shapes whether staff view substance use as a reason to tighten eligibility, restrict access, or demand abstinence before support. It also shapes whether people with lived experience feel safe disclosing their needs. In practice, stigma narrows the clinical conversation before it can begin.
Workforce support may determine whether integration is real or rhetorical
Workforce challenges surfaced as one of the four main barriers, and the implications are practical. Housing First programs can be asked to absorb more clinical complexity without receiving the staffing, training, supervision, or peer support required to do so well. Without that infrastructure, integration risks becoming a slogan rather than a service model.
The workshop’s core components make the staffing issue impossible to ignore. Participants identified person-centred and flexible approaches, foundational support for the workforce, and integrated and collaborative care systems as the pillars of effective substance use health integration. Those priorities point toward a model in which staff are not expected to improvise around every crisis. They need clear pathways, shared goals, and the backing of systems that can respond to changing needs without punishing the client for complexity.
A flexible approach matters because substance use trajectories are not linear. People may seek treatment, pause, return to use, reduce harm, or pursue recovery-oriented goals that shift over time. Housing First works best when services can move with those changes rather than forcing people into one static pathway. In that sense, flexibility is not a soft value. It is a clinical requirement for engagement.
Policy, funding, and data systems can either enable care or block it
Restrictive policy and funding environments were identified as another major obstacle. Programs cannot deliver integrated care if funding streams reward narrow service silos, limit staffing configurations, or fail to support culturally safe and low-barrier care. Policy design shapes what frontline staff can actually do, and whether they can sustain integrated work over time.
Equity-informed use of data emerged as an opportunity for progress. Done well, data can reveal which groups are being left behind, where service pathways break down, and how resources should be adjusted. Done poorly, data can be used in ways that intensify surveillance without improving access. The workshop’s framing suggests a clear preference for data systems that support accountability, adaptation, and fairness rather than control for its own sake.
Flexible model adaptation also ranked as an opportunity. Housing First is evidence-based, but evidence-based does not mean frozen in place. Communities differ in population mix, service availability, cultural context, and policy constraints. A rigid implementation strategy may preserve the label while losing the function. Adaptive design allows housing, health, harm reduction, treatment, recovery, peer, and community supports to be organized around individual goals instead of institutional convenience.
The model only works when the person defines the goal
The conclusion reached by this workshop was blunt in clinical terms. Effective integration requires a fundamental shift toward more person-centric systems: low-barrier, culturally safe models that organize housing, health, harm reduction, treatment, recovery, peer, and community supports around self-defined goals.
For people with significant substance use health needs, that matters because housing stability alone does not resolve overdose risk, withdrawal, stimulant-related psychosis, alcohol-related harm, or the daily strain of managing addiction in an unstable system. A Housing First program that treats substance use as peripheral may secure a lease but still leave the underlying health crisis untreated. A program that integrates care can respond to both at once, without making housing contingent on abstinence.
The workshop also placed lived expertise at the center of the solution. That is more than a governance preference. People with lived and living experience understand where service designs fail, which interactions build trust, and how policy choices appear on the ground. Their role is essential if integrated systems are meant to be responsive rather than merely well intentioned.
The study does not measure a clinical endpoint, and it does not claim that one standardized integration model will work everywhere. Its value lies elsewhere: it maps the operational barriers that repeatedly weaken care for people experiencing homelessness and substance use harms, while identifying the components most likely to make Housing First programs clinically usable for that population. The unanswered work now sits with policy makers, funders, and service systems that must decide whether integration will remain aspirational or become routine practice.
