Who this guide is for
Why GTA Businesses are Targeted
Cybercriminals often target businesses in prosperous hubs like Vaughan and Toronto because they assume these offices handle high-value transactions but have weaker IT defenses than major banks.
A single breach can cost a GTA small business an average of $50,000 in recovery costs, lost billable hours, and reputational damage.
Medical Clinics
Ensuring PHIPA compliance and protecting sensitive patient records.
Accounting Firms

Real-world scenario
A Typical Local Attack Scenario
An office manager at a Vaughan engineering firm receives a "missed invoice" email. They click a link, enter their Microsoft 365 credentials on a fake login page, and within 2 hours, the attacker has set up email forwarding rules to intercept client payments.
Without MFA or sign-in monitoring, this breach often goes unnoticed for weeks until a client reports a payment issue.
