About AOS

Local people. Bigger possibilities.

From Grimsby, we help businesses across the GTA, Niagara and beyond get more from the technology they rely on.

AOS, today

More capability. The same care.

Our work spans IT, cloud compute, on-premises server management, network and office infrastructure, security, AI, software, print, business communications and managed handsets. We have in-house technical support, developers and AI expertise, with hands-on help for the equipment and networks your people use every day.

We work with small and midsize businesses, including professional services firms, from our head office and customer care centre in Grimsby. Our service area reaches across Hamilton, Niagara and the GTA, with engagements beyond the region.

Our mission

Profit, productivity and peace of mind.

We apply technology to drive profit, productivity and peace of mind for our clients.

That means understanding what is getting in the way, choosing an approach that fits the business and staying involved after the installation. Our engagements flex around the customer, from a specific project to ongoing support.

A stronger foundation changes what is possible.

Our own modernization journey has shaped the way we work. Legacy infrastructure, difficult onboarding and scattered systems make it harder to manage a business and adopt new technology.

An identity-first approach brings access and applications around the people using them. With clearer control and less technical debt, it becomes easier to see what is happening and make the next change.

We see technology as an ongoing journey. The priorities evolve with your business, and so does the work.

Working together

Flexible engagements, built around the help you need.

    Keep your existing IT team and bring AOS in where you need extra capacity or specialist help. Together we can work on infrastructure, security, AI and the projects that keep getting pushed back.

  • A specific project
