Do You Think Your Partner Is Being Unfaithful?

Do You Think Your Partner Is Being Unfaithful?

Every relationship is different, but you are best placed to see signs that something is different. Trust your instincts if they tell you your spouse or partner is cheating. The signs below are indicators of a cheating spouse, especially if there is a marked deviation from their usual behavior.

  • Sudden interest in appearance
  • Using the phone or computer secretly or adding a password
  • Unexplained periods when your significant other cannot be reached
  • Odd expenses and charges on credit cards or personal savings accounts
  • Sudden increase or decrease in sex, or changed sexual preferences
  • Hostility towards you and your relationship
  • Fading emotional intimacy
  • Big changes to daily schedules

Many of these signs now surface first on a phone. For the data behind app, social-media, and messaging-based infidelity, see our Digital Infidelity Report.

Think Before You Snoop — Why DIY Backfires

Accusing a partner, whether or not they are cheating on you, without evidence can wreck relationships. It may also put you in physical danger. Too often, people end up saying something in shouting matches that can affect their alimony and child support.

Let Discreet Investigations work on your behalf to get you the answers you need. We will work in a discreet manner and report directly back to you. Don't put yourself in physical danger or break the law by trying to do this yourself.

Following someone by vehicle or any other means in today's society can lead to criminal charges. Depending on the police service and the circumstances, a number of charges can be laid — from stalking and mischief to criminal harassment. These are only some of the charges that police officers can and will criminally charge you with based on their investigation. This can also lead to restraining orders from partners and court orders keeping you away from your children.

Showing up unannounced or uninvited at someone's workplace or residence can be interpreted as stalking or harassment. This all becomes relevant when you are going through a separation, divorce, and custody or property issues before the courts. You do not want criminal charges filed against you while dealing with family courts — it can strongly weigh on the outcome of your proceedings. Remember, an accusation can be very damaging; one has to prove their innocence, which is not necessarily easy.

Our investigators have decades of experience in both criminal and family law cases. We will get the information required to win your case in a legal and discreet manner, protecting you as our client.

  • Evidence may be excluded by the court
  • Criminal charges for spyware and electronic snooping
  • Intentional and unintentional snooping may be illegal
  • You can be made to pay thousands of dollars in compensation
  • Civil liability for invasion of privacy, intrusion, trespass and nuisance

Cheating Spouses Investigations FAQs

How long does a typical infidelity investigation take?
Most investigations run 1–3 weeks, depending on the subject's schedule and the behaviour we're documenting. Some cases resolve in a single surveillance shift; others need multiple operations over a month to build a clear pattern. We'll give you an honest timeline at the consultation — and we stop the moment you have what you need.

Is it legal to hire a private investigator to follow my spouse?
Yes. In Ontario, licensed private investigators are legally permitted to conduct surveillance in public spaces, document observable behaviour, and report their findings to the client. What's illegal — and what we never do — is trespassing on private property, recording private conversations without consent, placing tracking devices on vehicles we don't own, or installing spyware on phones and computers.

Can the evidence be used in court?
When it's collected by a licensed PI following provincial law, yes. Our investigators are licensed under the Private Security and Investigative Services Act, use court-admissible equipment, and produce signed reports with timestamped video and photo evidence that has held up in Ontario family courts.

Will my spouse find out I hired an investigator?
No. Discretion is the core of what we do. Our investigators use unmarked vehicles, civilian clothing, and counter-surveillance training to remain undetected. All client communication is confidential, and reports are delivered through secure channels.

What if I'm wrong and my spouse is faithful?
That's often the best outcome. Many of our clients come to us hoping to be proven wrong — and a meaningful share of the time, we document nothing suspicious and deliver a clean report. Either way, you get certainty and you can move forward without the weight of not knowing.

What are the most common signs of a cheating spouse?
Common indicators include phone secrecy and new passwords, unexplained absences, sudden interest in appearance, changes in intimacy, hostility about routine questions, and unfamiliar charges on shared accounts. None of these alone proves infidelity — but a clustered change in behaviour is what most clients describe before hiring us.

Can a private investigator find out who my spouse is cheating with?
Yes. A standard infidelity investigation identifies the third party where possible — name, vehicle, residence, workplace, and the nature of the relationship — through lawful surveillance and public-record research. This information matters for divorce strategy and, in some Ontario cases, for support and property-division arguments.

Will a private investigator install spyware on my partner's phone?
No. Installing spyware on someone's phone, computer, or other device is a Criminal Code offence in Canada, even between spouses. We do not install software, intercept communications, or access accounts you aren't authorized to access. We rely on lawful surveillance, observation, and public-record research that holds up in court.

Should I hire an investigator before or after starting divorce proceedings?
Before. Evidence gathered before your spouse is alerted to a divorce is far easier to obtain — patterns of behaviour are still routine, and the subject isn't on guard. Once papers are served, behaviour shifts. Most family lawyers recommend confirming infidelity quietly first, then filing with evidence already in hand.

How does cheating evidence affect a divorce settlement in Ontario?
Ontario is a no-fault divorce jurisdiction, so adultery alone won't change property division. But infidelity evidence often matters for cohabitation timelines that affect support, dissipation of marital assets on an affair, custody implications when a third party is around the children, and credibility in negotiations. Talk to your lawyer about how it applies.

Can my spouse find out I hired a private investigator through court disclosure?
Generally no. Investigation reports prepared at your lawyer's direction are typically protected by litigation privilege until you choose to disclose them. If you commission the investigation directly, talk to your lawyer first about how to structure the engagement so privilege attaches. We coordinate with counsel routinely.
