IT Support & Outsourced IT Services in Toronto & the GTA
Proactive IT Support, Cybersecurity, and Strategic IT Planning for GTA Businesses – Delivered at a Predictable Monthly Cost.
Third Octet is a Mississauga-based IT support and managed services provider helping small and mid-sized businesses across the Greater Toronto Area reduce downtime, strengthen cybersecurity, and scale with confidence. Whether you need a fully outsourced IT department or support alongside your existing internal team – we adapt to your business, not the other way around.
We support organizations throughout Downtown Toronto, the Financial District, North York, Etobicoke, Scarborough, Mississauga, Vaughan, and surrounding GTA communities.
Is Outsourced IT Support Right for Your Toronto Business?
Outsourced IT support is ideal for Toronto and GTA organizations that rely on technology to operate and grow – but are frustrated by downtime, reactive support, or increasing cybersecurity risks.
Our services are built for businesses that:
- Have 10–150 employees and depend heavily on Microsoft 365 and cloud systems
- Need stronger cybersecurity and compliance controls
- Are outgrowing break-fix IT or a single internal IT person
- Want predictable monthly IT costs with no surprise bills
- Require strategic IT guidance – not just troubleshooting
- Have an internal IT team that needs additional depth and coverage
If technology issues are slowing productivity or creating risk, proactive IT management becomes a business necessity — not a luxury.

We manage your IT like it’s our own – so your team can focus on driving revenue and serving customers.
Do you work with existing in-house IT teams?
Yes. Many of our clients have internal IT staff. We complement their efforts by handling monitoring, maintenance, or specialized projects so they can focus on strategy and innovation. It’s a true partnership — not a takeover.
What’s included in IT Support services?
Our services cover everything needed to keep your business running smoothly and securely – helpdesk and user support, device and endpoint management, data backup and recovery, and Microsoft 365 administration. We also monitor your infrastructure, manage updates and patches, and provide cybersecurity protection so your team can focus on what they do best.
For our complete list of services and pricing see Workplace Suite.
Do you offer cybersecurity protection?
Absolutely. Every engagement includes security by design: from managed endpoint protection and Microsoft 365 security management to email filtering and proactive monitoring. Our goal is to safeguard your business data, users, and reputation without adding friction to your day-to-day work.
What makes Third Octet different from other MSPs?
We don’t just manage technology – we empower people. Our focus is on creating better work experiences through proactive IT, thoughtful automation, and human-centred support. We view ourselves as a full-circle partner, ensuring technology quietly powers your success instead of demanding your attention.
Do you include data backup and disaster recovery?
Absolutely. Data resilience is a core part of our managed IT service. We provide reliable server and cloud backup solutions with active monitoring and routine testing. With system-wide maintenance, your data never slips through the cracks. Should downtime or data loss occur, your systems and files can be quickly restored with minimal disruption. Plus, your disaster recovery plan is continuously updated to reflect any changes across your environment.
What are your support hours?
Our standard support hours are:
-
Monday–Friday: 8:00 AM – 6:00 PM ET
Outside of these hours, you’ll still have access to:
-
Emergency after-hours support (for critical events)
-
24/7 monitoring and alerting, so issues are identified quickly even when your team is offline
Most clients also meet with us monthly or quarterly for proactive planning, so support isn’t just reactive — it’s built around preventing problems before they hit your team.
Can you support remote or hybrid teams?
Definitely. We have a wealth of experience managing remote, hybrid, and onsite teams.
Our expertise dates back to 2007, when our company was founded with an exclusive focus on delivering remote workforce solutions. Over the past 16 years, we’ve honed these skills, making us leading North American experts in this space. Our philosophy is that work is not a place, and we have the proven technology and successful track record with Canadian brands to ensure your team has seamless productivity and collaboration from anywhere.
Do you provide onsite IT support in Toronto?
Yes. While most issues can be resolved remotely, we provide onsite support across the Greater Toronto Area when hands-on help is needed – including hardware troubleshooting, network issues, workstation setups, and project work.
Because we actively monitor and manage your systems, onsite visits are usually planned (not emergencies), but when something does require a physical presence, we’ve got you covered.
Can you help with IT budgeting and strategic planning?
Yes, we do. We support IT budgeting and high-level strategic planning through a combination of Technology Business Reviews (TBRs), monthly cadence meetings, and our technology portfolio.
During TBRs, we work closely with you to assess your current technology landscape, identify opportunities for improvement, and recommend solutions that align with your business goals and budget. Monthly cadence meetings keep communication open and ensure you stay up to date on technology trends and best practices.
Our technology portfolio provides a clear view of available products and services—helping you make informed, strategic decisions about your IT roadmap and investments. Together, these touchpoints ensure your technology continuously supports your long-term business direction.
