How long a private investigation takes depends on the case type, how much information you provide on day one, and whether the subject cooperates, travels, or actively hides. Some Ontario files produce usable results in a few days. Others need weeks of surveillance, records work, or multi-province coordination. Investigation Hotline is a licensed Ontario firm. This page explains realistic timelines. For the full hiring checklist and other FAQs, see our private investigator FAQ and our process.
What usually decides how long an investigation takes?
Duration is driven by scope, not slogans. A simple public-records background check can finish faster than continuous surveillance on someone with irregular hours. Missing-person locates vary with starting data. Financial or asset work can stretch when records sit in other provinces. Legal limits also matter: investigators cannot skip privacy rules to save time.
Who should read this: clients comparing quotes and wondering why one firm quotes days and another quotes weeks.
What you get: typical ranges by case type, what speeds or slows a file, and how updates usually work.
What this is not: a fixed price list or a guarantee that every case finishes in 72 hours.
How long do common investigation types take in Ontario?
- Surveillance (infidelity, activity verification): often measured in shifts over several days or weeks until a pattern appears. Short bursts can work when habits are predictable; irregular schedules take longer.
- Background checks: many straightforward checks resolve in days when identifiers are clean; deeper employment or court history can take longer.
- Locates / finding people: days to weeks depending on last known address, digital footprint, and whether the person is avoiding contact.
- Asset identification: often longer when property, vehicles, or accounts span multiple jurisdictions.
- Workplace or insurance files: timelines follow court, insurer, or HR deadlines plus evidence quality requirements.

What speeds up a private investigation?
Clear objectives, accurate names and photos, known workplaces and vehicles, and written permission where required all shrink dead ends. Clients who share dates, addresses, and prior evidence help investigators plan efficient shifts instead of guessing. Early contact with your lawyer also prevents mid-case scope changes that restart the clock.
What slows an investigation down?
Vague goals (“just find out everything”), incomplete identifiers, subjects who change routines after a tip-off, multi-city travel, and DIY confrontations that alert the subject all add time and cost. Uncooperative third parties and court-ordered limits can pause work. Cross-province evidence needs licensed partners in each jurisdiction, which adds coordination time.
How is timeline related to cost?
Longer files usually cost more because investigators bill for hours, travel, and partner work. A short, well-scoped surveillance plan is cheaper than open-ended watching. Discuss budget and stop points at intake. For Ontario pricing context, review private investigator rates before you assume a one-week file and a one-month file cost the same.
Ask what happens if the subject leaves town mid-file, whether travel days are billable, and whether unused retainer hours roll or expire. Clear commercial terms prevent timeline surprises that feel like cost surprises.
When should you expect updates during the investigation?
Reputable firms set reporting intervals in the engagement letter: after each surveillance shift, at weekly milestones, or when a finding changes strategy. Ask how you will receive updates (call, encrypted email, written memo) and who is authorized to hear them. Silence is not a status report; if you have heard nothing past the agreed window, ask for a check-in.
After fieldwork ends, allow time for report writing, exhibit labelling, and quality review. A polished report often takes additional business days beyond the last surveillance shift. If counsel needs something for a hearing date, say so at intake so the timeline includes that deadline.
Can a private investigation finish in one day?
Sometimes. A single productive surveillance day, a quick locate with strong starting data, or a limited database review can answer a narrow question. Most serious family or corporate matters need more than one sitting so findings are corroborated and documented. Anyone promising a complex file “done tomorrow, no matter what” should raise a red flag.
Frequently asked questions
Does a longer investigation always mean better evidence?
No. Extra days help when patterns need confirmation. Wasted hours without a plan do not. Scope and method matter more than calendar length alone.
Will the investigator tell me an exact end date on day one?
You should get an estimated range and decision points, not a fake hard deadline. Real files adjust when the subject changes behaviour.
Do holidays or weekends change timelines?
Surveillance often runs evenings and weekends when subjects are free. Office-based research may follow business-day schedules. Ask how holiday coverage works for your case type.
