Institutional AI

Sovereign AI for Ontario institutions that can't compromise on data

For Ontario public-sector bodies, hospitals, universities and Toronto enterprises, we design AI platforms that keep data in Canada, enforce tenant isolation at the database level, and pass security review, delivered through a structured four-stage program.

Capabilities

Enterprise-grade by architecture, not by promise

  • Postgres row-level security

    Multi-tenant isolation enforced inside the database, so one department can never query another's data, even through a bug.

  • Sovereign deployment

    Private cloud in Canadian regions (Toronto, Montréal) or on-premise, with open-weight model options.

  • Role-based access

    SSO integration and granular permissions mapped to your organisational structure.

  • Audit trails

    Every prompt, retrieval and action logged for compliance and internal review.

  • Governance frameworks

    AI use policies and risk assessments aligned to PIPEDA, PHIPA and FIPPA/MFIPPA where they apply.

  • Security review ready

    Architecture documentation and threat models prepared for your IT security team.

Multi-tenant security

Isolation you can verify

Row-level security policies travel with the data. Each request carries a tenant context, and Postgres refuses to return any row outside it.

policy.sql
ALTER TABLE documents ENABLE ROW LEVEL SECURITY;

CREATE POLICY tenant_isolation ON documents
  USING (tenant_id = current_setting('app.tenant_id')::uuid);

-- Every query from the AI layer is scoped automatically:
SET app.tenant_id = '…';  -- set per request from the verified session

Engagement framework

Four stages from strategy to scale

Each stage ends with a decision gate, so you commit budget only as value is proven.

  1. 01

    Assess

    Readiness review across data, infrastructure, policy and people. Use cases ranked by value and risk.

  2. 02

    Architect

    Sovereign reference architecture, security model, governance framework and business case.

  3. 03

    Pilot

    One high-value use case built on production-grade infrastructure and measured against agreed KPIs.

  4. 04

    Scale

    Roll out across departments with training, change management and an internal centre of excellence.

Reference stack

  • PostgreSQL + RLS
  • pgvector
  • Self-hosted LLMs
  • n8n
  • Keycloak / Entra ID SSO
  • Kubernetes / Docker

FAQ

Questions we hear most

What does sovereign AI mean?

Sovereign AI means your data, models and infrastructure stay under your jurisdiction and control, hosted in Canada, with no dependency on sending sensitive data to third-party services.

Why row-level security instead of separate databases?

Postgres row-level security enforces tenant isolation inside the database engine itself, giving strong guarantees while keeping one maintainable platform. Separate databases remain an option for the most sensitive tenants.

Can we start small?

Yes. The Assess stage is a fixed-scope engagement, and nothing beyond it is committed until you've seen the findings and business case.
