Canada has taken another major step in the way it approaches cybersecurity. With the adoption of the Critical Cyber Systems Protection Act, the federal government has established a framework that will require certain organizations to better protect critical systems, manage cyber risks involving suppliers, and report certain cybersecurity incidents.

At first glance, the legislation may seem primarily relevant to banks, telecommunications providers, energy companies, and critical infrastructure operators.
But one aspect deserves the attention of a much broader range of businesses: supply chain risk is now part of the equation.
An organization can have strong internal security measures and still be exposed through a supplier, software platform, service provider, or another partner with access to its systems. The new legislation explicitly recognizes this reality.
Your organization does not necessarily need to be directly subject to the Act to have a reason to follow its implementation.
A New Law, With One Important Distinction
The Critical Cyber Systems Protection Act received Royal Assent on June 15, 2026. It establishes a new framework designed to protect critical cyber systems associated with services and systems considered vital to national security or public safety.
At the time of writing, however, there is an important distinction: the Act is not yet in force. (Source: Government of Canada)
It would therefore be premature to suggest that affected organizations must already comply with all of these new requirements.
Nevertheless, the legislation provides a clear indication of the federal government’s direction. Protecting critical infrastructure is no longer simply about securing an organization’s internal systems. It also involves addressing risks arising from supply chains and third-party products and services.
And that is where businesses connected to these organizations should start paying attention.
Who Will Be Directly Affected?
The Act concerns critical cyber systems used in federally regulated sectors.
The critical services and systems listed in the legislation include telecommunications services, certain interprovincial or international pipeline and power line systems, nuclear energy systems, certain transportation systems, banking systems, and clearing and settlement systems.

This does not mean that every Canadian business will automatically become subject to the Act.
The government will be able to designate classes of operators to which the various requirements apply. These designated operators will then have responsibilities related to protecting the critical cyber systems they own, control, or operate.
For organizations doing business with these sectors, the relevant question is therefore not simply:
“Are we directly subject to this legislation?”
There is another question worth asking:
“Do we do business with an organization that could be?”
Supply Chains Are Becoming a Cybersecurity Issue
This is arguably one of the most relevant aspects of the new legislation for organizations that will not be directly regulated.
The Act provides that designated operators will need to identify and manage cybersecurity risks associated with their supply chains and their use of third-party products and services. When such risks are identified, operators will be required to take measures to mitigate them. (Source: Government of Canada)
Consider a simple example.
An organization operating critical infrastructure relies on an external company to manage an application, host certain data, or provide technical support. That company, in turn, relies on several cloud services, software platforms, and technology partners.
A vulnerability affecting one of those partners can potentially create risk further up the chain.
The cybersecurity of a large organization can therefore depend, in part, on the security practices of much smaller businesses.
That is why the impact of this type of legislation can extend beyond organizations that are directly regulated.
What Your Clients May Want to Know
Simply supplying products or services to a regulated organization does not automatically make a business subject to all the requirements of the Act.
That distinction matters.
However, because designated operators will be expected to manage risks associated with suppliers and third-party services, it is reasonable to expect that some organizations may eventually strengthen their supplier assessment processes.
That could mean asking more questions such as:
- Do you use multi-factor authentication?
- How do you manage administrator accounts?
- Do you have an incident response plan?
- How do you protect and test your backups?
- Which employees have access to client data?
- How do you assess your own suppliers?
- Can you quickly detect and report a security incident?
Being able to answer these questions clearly can become more than a technical exercise. It can help reassure clients that are themselves expected to better understand and manage their digital risks.
Cybersecurity Incidents Will Also Require Attention
The Act also establishes a cybersecurity incident reporting mechanism for designated operators. (Source: Government of Canada)
The objective is straightforward: when a critical system is compromised or at risk of being compromised, the organization needs to be able to detect the incident, limit its impact, and follow the applicable reporting process.
But once again, consider the supply chain.
If an incident originates with an external service provider, that provider’s ability to recognize the problem quickly and communicate relevant information becomes important to its client.
Every organization can therefore ask itself a very simple question today:
If we discovered an intrusion at 9 a.m. tomorrow, would we know exactly who to call, what to isolate, and which clients to notify?
If answering that question requires a meeting to figure out the response, there is probably work to be done.
Preparing Without Turning Your Business Into a Fortress
Responding to every new regulation by purchasing more security software would be counterproductive.
A better approach is to start with the fundamentals.
Identify the systems and data your organization cannot operate without. Document who has privileged access. Enable multi-factor authentication wherever it is available. Make sure backups can actually be restored. Determine who has decision-making authority when an incident occurs.
Then look at your suppliers.
Which partners can access your data or systems? What would happen if one of them were compromised? Can you quickly revoke their access? Is someone within your organization responsible for managing these relationships?
Answering these questions does not necessarily require a massive compliance project. More importantly, it helps turn cybersecurity into a business process rather than simply a collection of security tools.
Cybersecurity Is Also Becoming a Matter of Trust
For years, businesses could view cybersecurity primarily as an internal concern: protecting computers, passwords, and data.
That perspective is becoming increasingly difficult to maintain.
Businesses are interconnected. A cloud application processes sensitive information. Business software communicates with other platforms. A payment system depends on external services. And each of those providers may, in turn, depend on other technologies.
The Critical Cyber Systems Protection Act illustrates this shift well: protecting an organization also means understanding the dependencies surrounding it.
For businesses in Quebec, the message is not to panic over a new regulatory obligation that may not even apply directly to them.
The better approach is to recognize the signal.
Large organizations affected by the legislation will need to pay greater attention to supply chain risks. Being able to demonstrate structured cybersecurity practices could therefore become increasingly important in certain supplier-client relationships.
The real question may no longer be simply:
“Are we adequately protected?”
It may increasingly become:
“Can we demonstrate it to our clients?”
If these questions reveal uncertainties within your organization, the specialists at Mon Technicien can help you gain a clearer picture. Our team works with businesses across Quebec to assess cybersecurity risks, strengthen IT environments, and implement security practices adapted to their operational reality.
