Private Investigation Services

Covert Surveillance

Need to discreetly monitor a person, location, or activity without their knowledge? Our covert surveillance services use proven techniques to gather clear, admissible evidence while remaining undetected. Whether confirming suspicions, documenting behaviour, or protecting your interests, we operate with professionalism, confidentiality, and legal compliance. You’ll receive detailed reports and, when applicable, high-quality photo or video evidence tailored to your case.

Address Search

Need to locate someone’s current or previous address? Our address search service provides accurate and up-to-date location information using trusted databases and investigative methods. Whether you're trying to reconnect, serve legal documents, or verify residency, we can help you find the address you need, discreetly and legally.

Spouse Infidelity

Spouse infidelity is a highly delicate matter, and we understand this like nobody else. That is precisely why, at Wolf Group, we treat each adultery case with great respect, care, and complete confidentiality. You can rest assured that everything our private investigators see and capture will never be shared with any third party unless you request us to do so.

Child Custody

If you are a parent and you disagree with your former spouse regarding child custody, the court will make the final decision. You must gather solid evidence that the other parent cannot fulfill their responsibilities to justify your rights. At Wolf Group, we can help you with this sensitive matter quickly, efficiently, and professionally.

Background Checks

If you are about to hire an employee or rent your property to a new tenant but do not feel confident, you must perform a background check to ensure you will be dealing with an honest and reputable person you can trust. Wolf Group employs various measures to deliver quick and efficient results.

Electronic Bug Detection

Privacy invasion and illegal electronic surveillance may badly affect your personal life or business. At Investigator 911, we provide Technical Surveillance Countermeasures (TSCM). We will quickly detect bugs, hidden cameras, and recording devices installed within your premises and eliminate non-legitimate and harmful surveillance activities. Do not take the chance; debug your office or residential space today.

Missing Assets

This type of private investigation may be required in cases involving divorce (when one spouse fails to disclose their assets fully), unpaid child support, or settling business disputes (including unpaid debts). At Wolf Group, we can quickly help you locate missing individuals, hidden property (such as real estate), or financial assets.

Missing Persons

If you have decided to reunite with a relative you haven’t seen for decades or, God forbid, your kid has left the house and you have no idea where they are, you may decide to hire a private investigator. At Wolf Group, we possess the necessary resources and expertise to locate missing individuals throughout Canada. Please let us know what's going on, and we will start an investigation ASAP.

Undercover Operations

Our law enforcement and military experience enables us to conduct high-quality undercover operations, which may be necessary when handling complex private investigation cases. These operations help us discover various types of illegal activity or establish a fact vital for legal proceedings. We are ready. Are you?

Insurance Fraud

When an individual makes a false claim on an insurance policy (medical, automotive, or real estate insurance), a private investigator must prove the claim was fraudulent. At Wolf Group, we are perfectly equipped to gather all the necessary information that will enable you to resolve any insurance fraud case successfully.

Secret Shopper

When you run a service or retail company, you never know what happens when you are off-site. Unless you check your staff to ensure they comply with specified requirements, low-quality service can damage your business's reputation. At Wolf Group, we can engage a secret shopper and provide you with a detailed report.

Lost Pet Search

If you have ever lost your cat, dog, or other pet, you know how painful and frustrating it is for all family members. Sometimes, pets return home or get found by one of your neighbours, but unfortunately, that is not always the case. Luckily, our private investigators know how to deal with these situations. Act now to increase your chances of finding your little friend.

Legal Support When You Need It

Every private investigation case is different. In some matters, you may need key information, discreetly gathered, so that no one ever knows you hired a private investigator. In other situations, a formal investigation may be necessary to support your position in court. All of our investigation packages include an official report that is admissible in court. Our Premium Packages also include free investigator testimony before a judge, if required. Because the government licenses private investigators, their reports and testimony can serve as credible, persuasive evidence in legal proceedings. We are on your side.

The Importance of Data Accuracy in Private Investigation

What Our Clients Say

At some point, I started to feel that my husband had someone else. He has changed his daily routines and even completely stopped having dinner at home. Several times I even noticed that he smelled of a woman’s perfume. My friend advised me to contact the private investigators of the Wolf group. The guys quickly got involved in the case. I quickly realized what was going on. I have all the evidence, photos, and videos. Now my lawyers are working on the case.

Diana Porter

I am working in construction. Obviously, it is not easy to find projects or win a tender in times of crisis. In addition, I have a responsibility to provide my employees with work. So, not long ago, I received a favourable offer for a subcontract for construction. I decided to take the risk. Sometimes you gotta do what you gotta do. And then, almost at the last moment, my friend advised me to check the contractor’s background for a small fee. I agreed reluctantly. I contacted the Wolf Group private investigation agency.

Imagine my surprise when I received the investigation report. It turned out that the contractor was heavily in debt. He was apparently under trial and in bankruptcy proceedings. I withdrew from this shady contract right away and ordered my employees to return our equipment to the lot. The contractor hired workers of our competitor.

A month later I learned that employees had not been paid and that my competitor had to cover their salary arrears out of his own pocket. The damage was about $800,000. I was so grateful for the private investigation service that I compensated Wolf Group private investigators with a little extra. Thank you, guys! From the bottom of my heart.

I am from Quebec City. My daughter graduated from college and decided to look for a job in Montreal. She told me that she was staying at a friend’s house. Two weeks later, my daughter stopped communicating with me. Her cell phone was turned off. And since this was not sufficient enough to go to the police, I decided to contact the Wolf group investigation agency located in Montreal. The private investigators worked quickly. I do not know how, but they found my daughter’s girlfriend. The investigators found out that she was a drug addict and that her boyfriend stole my daughter’s money and a cell phone, which she allegedly lost. My daughter was taken in by another girlfriend. That’s where the private investigators found my daughter. I am very grateful for the professional investigation service.

Quebec

I had to get a background check of employees I wanted to hire. There were two candidates. Both had good references and I did not have a preference. Also, I was aware of the value of each of them and the fact that I could miss a good opportunity. I decided to contact Montreal’s private investigation agency Wolf Group. In the shortest possible time, I got the background checks from the previous places of work and even the results of the police check. The information I received from the private investigators helped me to quickly make the right decision and choose the best candidate to hire.
