Ontario's Trusted IT Partner
for 20+ Years
We're not just an IT vendor — we're a long-term business partner who takes your technology as seriously as you take your business.
Built on Trust.
Driven by Results.
A&S System Consultants was founded with a simple belief: small and mid-sized businesses deserve the same quality of IT support as large enterprises — without the enterprise price tag.
For over 20 years, we've served businesses across Mississauga and Ontario, building long-term relationships based on transparency, rapid response, and genuine care for our clients' success.
Today, we're at the forefront of AI-powered IT management — helping our clients harness Microsoft Copilot, implement zero-trust security, and build the digital infrastructure they need to compete and grow.
Proactive First
We prevent problems before they happen. Our monitoring and maintenance approach means most issues are resolved before you even notice them.
Flat Fee, Full Service
No surprise invoices. One predictable monthly fee covers everything — so you can budget with confidence and call us as often as you need.
Security-First
Every recommendation we make starts with security. From network design to cloud migrations, we build protection in from day one.
People, Not Tickets
We know your business and your people. When you call, you talk to someone who knows your setup — not a call center reading from a script.
