How We Chose
1. Investigation Hotline

Services offered: Infidelity investigations, surveillance, computer forensics, workplace investigations, missing person cases, and more
Address: 1920 Yonge St Suite 200
Phone number: +1 416-205-9114
Business hours: Available 24/7
Investigation Hotline is a private investigation agency that has been in operation since 1988. With over three decades in the game, they offer a wide range of services that includes infidelity investigations, surveillance, computer forensics, and missing person cases.
One thing that really sets them apart is their use of drones and aerial surveillance. This tech-savvy approach allows them to gather evidence in a way that’s both efficient and discreet.
Another standout feature is their international investigations services. If you have a case that goes beyond Canadian borders, they have the expertise and resources to tackle it.
However, one problem I see is that they sometimes fail to respond to enquiries. It’s also disappointing that some of their clients encountered rude behaviour from their investigators.
We were very impressed with their efficiency and persistence
“We hired Mark and co to help us find a family member who had disappeared and was living on the streets. They found them within 24 hours. They were thorough and were in constant contact. They were also kind and empathetic. We were very impressed with their efficiency and persistence. I would highly recommend.”
-R S, Google Reviews
Our case was solved within 3 days
“Marc and his team have been nothing but amazing, not only did we have results within 24 hours, his team was very understanding and kind. Marc helped my family navigate through a tough time through his compassion and endless guidance. If it wasn’t for Marc and his remarkable team my family would not be at ease as we are today.
Thank you to Marc and his team’s great dedication to our family and situation. If it wasn’t for them we wouldn’t get the results we needed and that too within 24 hours. Our case was solved within 3 days. Couldn’t be more grateful for them. Thank You!”

2. Top Tier Investigations Inc

Services offered: Spousal infidelity investigations, insurance fraud, workplace claims, COVID-19 compliance, GPS tracking, and more
Address: 5000 Yonge St Suite 1901
Phone number: +1 416-549-4901
Business hours: Available 24/7
Another veteran private investigation agency worth checking out is Top Tier Investigations Inc. Their team has a combined experience of over 50 years and can assist you with investigating spousal infidelity and insurance fraud, filing workplace claims, and more.
One area where they really shine is family matters investigation. They’re well-versed in family law and can gather the evidence needed to win divorce proceedings and child custody cases.
They also provide COVID-19 compliance investigations to help businesses ensure employees adhere to ethical and legal standards, even in remote work environments.
On top of that, their GPS tracking services can assist in monitoring company vehicles, verifying routes, and ensuring valuable cargo reaches its destination safely.
That said, their services aren’t the cheapest option out there. Plus, because they’re so in demand, they tend to get fully booked quickly.
Very professional, diligent, & transparent
“Top Tier investigations is the standard for excellence. I had urgent documents to be served, & they over achieved w/ video evidence & sworn affidavit. Very professional, diligent, & transparent. I couldn’t have asked for a better experience & would definitely recommend them!! A+ 💯 Thank you”
-Steve Zabinski, Google Reviews
Top Tier was really there for me
“My ex had a backlog of unpaid child support and was claiming to be unemployed to avoid having to pay. I was in a desperate situation but Top Tier was really there for me. They were compassionate and very transparent about their services and ended up successfully proving my ex wasn’t being truthful about his work status. I couldn’t be relieved.”

3. Star Quality Private Investigations

Services offered: Infidelity investigations, background checks, corporate investigations, bug sweeping, life coaching, executive protection, and more
Address: 2425 Matheson Blvd E Suite 888, Mississauga
Phone number: +1 905-565-8884
Business hours: Available 24/7
Star Quality Private Investigations (SQPI) is an investigation agency with over two decades of experience. Founded by a team of former law enforcement professionals, they provide services like infidelity investigations, background checks, and corporate investigations.
What really caught my eye was their Case Support and Life Coaching service. They have their own life coach who can help clients navigate through the emotional challenges that may arise during an investigation.
Another good service they offer is Technical Surveillance Countermeasures. If you’re worried about hidden cameras or tracking devices invading your privacy, their team can detect and remove these threats.
Plus, if you believe your life is in grave danger, they can provide professional protection services.
One downside, though, is that their final pricing sometimes ends up being higher than the initial quote. This is because of extra fees that aren’t always explained clearly.
The investigators always delivered prompt updates
“Adrienne and Star Quality were an excellent company to work with! The investigators always delivered prompt updates. Adrienne was great to work with, she went above and beyond and always kept it professional. I would highly recommend anyone looking for a private investigation service to go with Star Quality!”
-Richard Crippin, Google Reviews
They worked diligently and efficiently on giving me the answers I needed
“I highly recommend Star Quality! I hired this company a few months ago to investigate a personal matter. They worked diligently and efficiently on giving me the answers I needed. Although the results were traumatizing, Adrianne, the co-owner who is also a Life Coach, counselled me through the most difficult time of my life.Without hesitation, she was there for me whenever I needed her. She was genuinely concerned and would regularly check in to make sure I was okay and on track. She literally changed my life by redirecting my negative mindset to a confident and well adjusted person. Her motivational talks, insight and inspiration gave me the tools I needed to work on myself.”

4. Facts Investigations

Services offered: Insurance investigations, cheating spouse investigations, litigation services, assets location, background checks, and more
Address: 1 Concorde Gate Suite 702
Phone number: +1 416-655-3106
Business hours: Available 24/7
Facts Investigations has more than a decade of experience in the industry and can assist you with finding a missing person, investigating infidelity, examining corporate fraud, and more.
One of the things that stands out about them is their focus on litigation support. They can assist with preparing, filing, and serving legal documents on your behalf. Of course, they will also gather the necessary evidence to strengthen your case in court.
Another thing I like is that they also specialize in tracking down hidden assets, like real estate, bank accounts, and luxury vehicles. This service can be handy for things like divorce settlements or recovering debts.
However, please note that they may occasionally miss responding to enquiries. It’s a good idea to follow up with another email if you don’t hear back after 24 hours.
Amazing service provided
“Thank you! Really helped me with my journey and amazing service provided.”

5. The Investigators Group Inc.

Services offered: Workplace investigations, background checks, insurance investigations, loss prevention, electronic security, and more
Address: 130 Queens Quay E Suite 510
Phone number: +1 800-765-8348
Business hours: Available 24/7
For business owners who are having issues with theft, The Investigators Group Inc. is a solid choice. They’ve been around since 1995 and offer services like workplace investigations, background checks, and insurance investigations.
One of the main areas they excel at is loss prevention, especially for retail businesses. They’ve got trained loss prevention officers who know how to spot and handle shoplifters, as well as programs to investigate internal theft.
Their security services are also worth mentioning. From deploying undercover investigators who monitor employee compliance to offering electronic countermeasures for detecting and tracing corporate espionage or system hacking, their expertise is quite impressive.
That said, they’re more focused on business clients, so personal investigation services—like digging into a cheating spouse situation—aren’t really their strong suit. If that’s what you’re after, you might need to look elsewhere.
Could not ask for better service and understanding of our needs
“We used Investigators Group Inc. for a very sensitive project. Could not ask for better service and understanding of our needs. It’s rare to find a company that can work independently and provide real value.”
-Phil Sciuk, Google Reviews
This investigation company is very good at what they do
“This investigation company is very good at what they do. They’re investigators are professional, courteous and get the job done at a very reasonable price. I would recommend them to anyone looking for security or any other investigative work.”
-Alicia S Anderson, Google Reviews
