What makes a Montreal investigation different
Montreal investigations often involve bilingual communication, dense urban environments, multi-jurisdiction travel (Greater Montreal), and tight privacy expectations. A good case plan matters more than “doing more” – the goal is to collect the right evidence, not just activity.
That is why we focus on:
- A documented plan with clear objectives
- Lawful, ethical evidence collection
- Reporting designed for real-world use (HR decisions, insurance matters, family law, civil disputes, internal business decisions)

How it works in Montreal (step-by-step guide)
This section is intentionally practical. If you follow it, you save time and money.
Step 1 – Define the goal in one sentence
Examples:
- “Confirm whether the person is working while on paid leave.”
- “Verify whether cohabitation is happening regularly.”
- “Locate an individual for a legal matter.”
- “Assess the credibility of a person before a major decision.”
If the goal is unclear, investigations get expensive and messy.
Step 2 – Tell us the constraints
- Deadlines (court date, HR decision date, travel dates)
- Budget range
- What you already know, and what you only suspect
- Any risk factors (conflict, safety concerns, volatility)
Step 3 – We propose an investigation plan
You receive:
- Recommended method (surveillance, checks, locate work, OSINT, mixed plan)
- Expected timeline
- What success looks like
- What cannot be done, if applicable
- Quote and next steps
Step 4 – We execute and document
We work discreetly and keep communication clean:
- Updates at agreed intervals
- Evidence logged and organized
- Adjustments are made only when they improve results, not to inflate hours
Step 5 – You receive a final report
Typical deliverables include:
- Executive summary
- Chronological timeline
- Findings with supporting documentation
- Media evidence, when available
- Practical next-step recommendations
What we need from you (client checklist)
You do not need everything, but the more accurate your starting info is, the better the results.
For a person:
- Full name, approximate age
- Recent photos
- Known addresses, vehicles, workplaces, schedules
- Social links and known associates (optional)
For a company case:
- Entity names and roles
- Known policy violations, dates, incidents
- Internal documentation you can share
- Objective you need to support (HR action, loss prevention, risk mitigation)
For locate work:
- Last confirmed contact
- Known addresses and phone numbers
- Any case reference and purpose (helps define the right approach)
What you can expect (timelines and cost drivers)
We do not sell fairy tales. Every case depends on facts.
Timelines depend on:
- Quality of starting information
- Predictability of the subject
- Complexity and geography (Greater Montreal travel)
- Whether the objective is verification or full pattern mapping
Cost drivers (honest list):
- How many unknowns exist
- Whether the subject changes routines
- Multi-day pattern confirmation requirements
- Urgency and scheduling constraints
If you want a precise number, we can only do that after a quick intake call. We provide a written quote before work starts.
Confidentiality, privacy, and compliance
We treat every investigation as sensitive by default. Your information is handled with care, limited to the purpose of the case, and retained only as needed for legitimate business and legal reasons.
If your case involves cross-border factors, we will flag any practical privacy considerations early, so you are not surprised later.
When to hire a PI vs when to call the police
Hire a PI when you need:
- Verification of facts and patterns
- Evidence for a decision, dispute, or prevention
- Discreet fact-finding without escalation
Call emergency services if:
- There is immediate danger
- A crime is happening now
- You need urgent intervention
We can support documentation, but we are not a replacement for emergency response.

“How to choose the right investigator in Montreal” (mini guide)
If you are comparing agencies, use this checklist:
- They clearly say what they will NOT do (illegal methods, hacking, unlawful tracking).
- They explain deliverables (report structure, evidence handling).
- They provide a plan, not just “hours”.
- They can explain why the method fits your objective, not just sell a service.
- They communicate professionally – clear scope, clear updates, no chaos.
If any of those are missing, you risk paying for activity instead of results.
