It is human nature to sometimes take for granted the services we expect to be there when needed. We turn on the tap and clean water flows. We flick a switch, and darkness is replaced by light. We may grumble about gas prices and traffic, but still our vehicles flow along highways controlled by complex networks of traffic signals, cameras, and connected infrastructure. With a few taps on a screen, we book flights, travel across borders, and ascend to cruising altitude without a second thought about the digital systems making it possible.

All of this — and more — falls under the umbrella of Critical Infrastructure. Public Safety Canada continues to define it as:

”…processes, systems, facilities, technologies, networks, assets and services essential to the health, safety, security or economic well-being of Canadians and the effective functioning of government. Critical infrastructure can be stand-alone or interconnected and interdependent within and across provinces, territories and national borders. Disruptions could result in catastrophic loss of life, adverse economic effects, and significant harm to public confidence.”

It is serious — and in 2025, more so than ever before.

Today, threats to critical infrastructure are no longer hypothetical risks discussed in boardrooms. They are active, evolving dangers. Cybercrime has become highly organized, driven by sophisticated adversaries using automation, artificial intelligence, and — on the near horizon — quantum computing capabilities to probe, exploit, and attack vulnerabilities in the systems we rely on every day.

There was a time when it was simply called infrastructure. Now, our energy grids, transportation systems, health services, financial institutions, and communication networks are all connected through digital ecosystems — and therefore, interconnected in risk. Our dependency on these digital ecosystems is what has truly put the “critical” in Critical Infrastructure.

Historical events serve as milestones for how far cyber threats have come:

• 2003 Northeast Blackout: A software failure cascaded into a mass power outage for millions across Ontario and the northeastern U.S.
• 2010 Stuxnet: A cyber weapon physically sabotaged Iranian nuclear operations, showcasing that code could cause real-world destruction.
• 2014 Korea Hydro & Nuclear Power Breach: Sensitive information theft demonstrated that no sector is off-limits.
• 2016 DYN DDoS Attack: A botnet-driven assault on a core internet service provider caused widespread outages across major sites like PayPal and Twitter.
• 2021 Colonial Pipeline Attack: A ransomware attack halted major fuel distribution in the U.S., creating shortages and public panic.

Since then, the threat landscape has dramatically accelerated, with ransomware-as-a-service, deepfake-driven phishing, supply chain attacks, and even early-stage quantum decryption threats emerging. The pace of innovation in cybercrime matches — and sometimes outpaces — our defenses.

Critically, it’s not just large corporations and governments that are vulnerable. Small and medium-sized businesses (SMBs), which form the heart of both local communities and national economies, have increasingly become attractive targets. Criminals know that many SMBs lack dedicated cybersecurity teams or enterprise-grade protection — making them easier prey and potential stepping stones to larger targets.

In 2025, cyber insurance is no longer optional for responsible risk management; it is essential. Modern cyber insurance policies go far beyond financial payouts — they provide access to breach response teams, forensic experts, public relations support, and even pre-incident risk assessments. For SMBs, this kind of coverage is often the critical lifeline that means the difference between recovery and collapse after a cyberattack.

What can be done to secure Critical Infrastructure — and protect businesses of all sizes?

It begins with mindset. Organizations must move beyond thinking of cybersecurity as a checkbox exercise. Adopting a when, not if approach fosters the kind of ongoing vigilance necessary in today’s environment.

Defense in depth strategies must be implemented — with layers of protection across people, processes, and technology. Cyber resilience must be baked into every operation, from boardrooms to shop floors.

Strategic partnerships and pre-incident engagement with cyber insurance providers, law enforcement, and threat intelligence sharing organizations like the Canadian Cyber Threat Exchange (CCTX) are vital. Waiting until after an incident occurs to build relationships is too late.

International cooperation must also continue to evolve, especially as AI-driven threats and the future implications of quantum computing loom. Our adversaries innovate constantly — so must we.

Justice Archie Campbell’s insight from 1996 still resonates today:

“A case management system is needed that is based on cooperation, rather than rivalry, among law enforcement agencies.”

Campbell was ahead of his time. Cooperation — between private sector, public sector, law enforcement, insurers, and even international allies — is the only viable path forward.

As we move deeper into an era of interconnected infrastructure and intelligent adversaries, our collective responsibility is clear:

• We must secure Critical Infrastructure.
• We must strengthen and protect small and medium-sized businesses.
• We must embed cyber insurance into every organization’s cybersecurity strategy.
• And we must work together relentlessly to build a cyber-resilient future.

The Internet and the systems it powers have given us unprecedented opportunity. It’s now up to all of us to ensure they also remain safe, stable, and secure for generations to come.
