Canadian Cybersecurity Threat Landscape 2026 | Part 6 of 10
Data Breaches in 2026
Every business collects more data than they probably realise.
Customer details. Employee records. Quotes and invoices. Emails. Years of conversations and hard work.
It’s the information that keeps your business moving every day.
The problem is that cybercriminals know how valuable that information is too.
A data breach doesn’t just mean information has been stolen. It can interrupt operations, damage customer trust, and leave businesses dealing with financial, legal, and reputational consequences long after the initial incident.
This is Part 6 of our 10-part series based on our Canadian Cybersecurity Threat Landscape 2026 Report. In Part 5, we explored how cybercriminals increasingly target trusted vendors and suppliers to gain access to businesses. More often than not, they’re after one thing: your data.
Let’s take a closer look.
What Is a Data Breach?
A data breach happens when information that should be private is accessed, exposed, or stolen by someone who shouldn’t have it.
Sometimes it’s the result of a cyberattack.
Sometimes it’s caused by a phishing email, a weak password, or a simple human mistake.
It doesn’t always make headlines, but for the business affected, the impact can be significant.
Whether it’s customer information, financial records, employee details, or confidential business documents, once that information has been exposed, the potential harm can be difficult to undo.
That’s why preventing a breach is always easier than dealing with the consequences afterwards.
Why Are Data Breaches Increasing?
Businesses are more connected than ever before.
We work in the cloud, collaborate online, access files from anywhere, and rely on digital tools to keep everything running smoothly.
All of that makes day-to-day business easier.
It also means we’re storing more valuable information online than ever before.
At the same time, cybercriminals have become more sophisticated.
They’re using AI to create convincing phishing emails, exploiting weak passwords, and taking advantage of outdated software or poorly secured systems.
For many businesses, it isn’t one big security failure that leads to a breach.
It’s a series of small gaps that attackers know how to find.
YOUR DATA IS WORTH MORE THAN YOU THINK
Every business stores valuable information that cybercriminals want to access. A proactive cybersecurity strategy can help protect your data and reduce the risk of it falling into the wrong hands.

It’s easy to assume hackers are only interested in large corporations.
In reality, they’re looking for valuable information, wherever they can find it.
That might include:
• Customer contact details
• Employee records
• Financial information
• Payment details
• Login credentials
• Contracts and business documents
• Emails
Even if your business doesn’t store highly sensitive information, your email account or Microsoft 365 login could be enough to give attackers access to much more.
Every business has something worth protecting.
How Do Most Data Breaches Happen?
Not every data breach starts with sophisticated malware.
Many begin with everyday mistakes.
Phishing emails
An employee clicks a convincing email and unknowingly gives attackers access to business systems.
Weak or reused passwords
If the same password is used across multiple accounts, one compromised login can quickly lead to others.
Cloud misconfigurations
A shared folder or cloud storage account that’s accidentally left public can expose confidential information without anyone realising.
Lost or stolen devices
Laptops, phones, and USB drives often contain more business information than people expect.
Outdated software
Cybercriminals regularly exploit vulnerabilities that already have security updates available.
Keeping software up to date remains one of the simplest ways to reduce risk.
Human error
Sometimes it’s as simple as sending the wrong attachment to the wrong person.
Mistakes happen.
Having the right safeguards in place helps prevent those mistakes from becoming serious incidents.
The Real Cost of a Data Breach
The cost of a data breach isn’t just measured in dollars.
There’s the time spent investigating what happened, restoring systems, speaking with customers, managing legal or reporting requirements, and getting the business back up and running.
The 23andMe breach is a powerful example. Attackers used login details stolen in previous, unrelated breaches to access customer accounts between April and September 2023. When Canada’s Privacy Commissioner published the findings of its investigation in 2025, it reported that almost seven million people worldwide had been affected, including nearly 320,000 Canadians.
While most businesses won’t experience a breach on that scale, the lesson is the same. Once sensitive information is exposed, the impact goes far beyond the technical recovery.
Trust takes years to build, but it can be damaged overnight if customer information falls into the wrong hands.
That’s why protecting your data isn’t just about preventing cyberattacks. It’s about protecting your reputation, your customer relationships, and the business you’ve worked so hard to build.
COULD YOUR BUSINESS HAVE HIDDEN SECURITY GAPS?
Most businesses don't realise where they're vulnerable until it's too late. A free cyber assessment can help you uncover potential risks and strengthen your security with practical, tailored recommendations.
Talk to a Cyber Expert5 Ways Canadian Businesses Can Better Protect Their Data
The good news is that you don’t need an enterprise-sized IT department to improve your cybersecurity.
A few good habits can make a big difference.
1. Limit who has access to sensitive information
Not every employee needs access to every file.
Review permissions regularly and only give access where it’s genuinely needed.
2. Turn on multi-factor authentication
MFA adds another layer of protection if passwords are ever stolen or compromised.
It’s one of the simplest and most effective security measures available.
3. Keep your software up to date
Software updates often contain important security fixes.
Delaying updates gives attackers more time to exploit known vulnerabilities.
4. Back up your data regularly
Reliable backups can dramatically reduce downtime if the worst happens.
Just remember to test them regularly too.
A backup is only useful if you know it works.
5. Invest in proactive monitoring
Many cyber incidents show warning signs before they become major problems.
Having someone monitor your systems can help identify suspicious activity early and respond before it escalates.
