AI Agent Development Services We Offer in Montreal
Most agent work we take on in Montreal is the second attempt, after a demo impressed a steering committee and then could not be put in front of a customer. We build retrieval agents over bilingual corpora where French and English documents are indexed with language tags and the retriever is measured separately in each language, because a single blended score hides a French failure rate. We build document-extraction agents for the contracts, regulatory filings and maintenance records that arrive in both languages and often in the same file. We build voice agents with Quebec French recognition tested against real Quebec speech rather than European French samples. We build tool-using agents where every action against a system of record is idempotent, logged and reversible. And we build the boring layer that decides whether any of it survives contact with production: evaluation suites with fixed regression sets, tracing on every step, cost and latency budgets per task, confidence thresholds that route to a human instead of guessing, and an automated-decision notice wherever the agent's output materially affects a person. Where a model would otherwise see personal information, we scope de-identification before the call rather than after the incident.
Our AI Agent Development Development Process
We open with a week that produces a written definition of done, because agent projects fail most often on the absence of one. That means a task inventory with the volume and cost of each task today, a labelled evaluation set built from real cases rather than invented ones, a pass threshold agreed before any model is chosen, and a named human owner for every escalation path. Alongside it we run the Law 25 privacy impact assessment, which Quebec requires before an organization acquires, develops or overhauls an information system handling personal information, and a French-language review covering anything a customer or an employee will read. Build runs in two-week increments, and every increment is scored against the frozen evaluation set in both languages before it is shown to anyone, so progress is a number rather than an impression. Deployment is staged: shadow mode where the agent runs beside the human and its output is compared but not used, then assisted mode where a person approves each action, then autonomous operation inside a bounded task with a kill switch and a rollback that has been rehearsed. Chandigarh runs the long evaluation and red-team passes overnight so each Montreal morning starts with fresh results.
Process Discovery
1-2 WeeksWe sit with the people doing the work in {city} and record the real process — including the exceptions they handle by instinct, which are exactly what kill naive automations.
Tool Surface Design
1-2 WeeksEvery system the agent touches gets a typed, permission-scoped tool with its own rate limit and rollback path. The agent gets a narrow set of verbs, never raw admin access.
Build & Evaluate
3-6 WeeksThe agent is built alongside its evaluation suite from day one, using real tasks from your business with verified outcomes. Every change is scored before it ships.
Shadow Mode
2-3 WeeksThe agent runs against live traffic but commits nothing. We compare its proposed actions to what your team actually did and tune until agreement is high enough to trust.
Staged Autonomy & Run
OngoingAutonomy is released by risk band — reversible actions first, irreversible ones keeping a permanent human gate. Then we monitor completion rate, escalations, latency and spend.
Technologies We Use for AI Agent Development
Orchestration runs on LangGraph, the OpenAI Agents SDK or a plain typed state machine when the graph is small enough that a framework adds more risk than it removes, with Pydantic for typed contracts between steps and LiteLLM where model routing has to be swappable. Tracing and evaluation run on Langfuse, LangSmith or Arize Phoenix, and the traces are retained as evidence, not just as debugging output. Model selection follows residency and language: Claude and GPT models through Amazon Bedrock or Azure OpenAI in Canadian regions, Cohere where a Canadian-headquartered vendor is a procurement requirement, Mistral where native French performance matters, and self-hosted Llama or Mistral weights on Canadian GPU capacity where the data cannot leave a controlled environment at all. Retrieval runs on pgvector inside the existing Postgres where possible, or Pinecone, Weaviate or LanceDB where scale justifies a separate store. Voice agents use LiveKit or Vapi with Quebec French recognition and neural fr-CA speech. Everything deploys into AWS ca-central-1 or Google Cloud northamerica-northeast1, both in Montreal, or Azure Canada Central with Canada East in Quebec City, provisioned with Terraform and observed with OpenTelemetry.
