Co-managed IT · Toronto & the GTA
One or two people cannot run the help desk, deliver a migration, cover leave and stay across security at the same time. We add senior engineers where your team needs them, work in your tools, and hand back the notes. Your team stays in charge.
Co-managed IT services for businesses across Toronto, Markham and Canada with an internal IT team of one to five people.
Where we usually help
Your team stays in charge. We fill the gaps you choose, and we leave the notes behind.
When it helps
Co-managed IT is not all or nothing. Most teams start with one of these and add more later.
A Microsoft 365 migration, a new office network, a server retirement. Your team keeps the day-to-day running while we supply the engineers to deliver it.
Three weeks of leave, parental leave or a resignation in the middle of a busy quarter. We cover the help desk and the systems in your tools, with your processes.
Security hardening, identity, firewalls, backup design or an ERP rollout. We bring the depth your team does not need to carry full time.
Your one or two people cannot be on call every night and weekend without burning out. We pick up the calls and leave notes for the morning.
Who owns what
Choose who should own each job. Copy the result and take it to your IT lead, or bring it to our first meeting — we will agree the real split with them and write it down.

A starting point, not a contract. Nothing here commits you to anything.
The honest question
Sometimes that is the right answer, and we will tell you so. If what you need is a second pair of hands on the help desk for forty hours a week, hire. If what you need is a security architect for two days a month, a cloud engineer for a migration and someone awake at 2am in March, one hire does not solve that.
Co-managed IT exists for the gap between what one person can cover and what the business keeps asking of them. Your team keeps the context nobody else has: which systems matter, who to call, how the business actually runs.

How it works
We sit down with your IT lead and write down who owns what, so nothing overlaps and nothing falls through.
We work in your systems with our own named accounts and multi-factor, so every change is traceable back to a person.
Our engineers work alongside your team, in your ticket queue, and document as they go rather than afterwards.
When a project ends your team keeps the notes and the know-how. The point is to leave you stronger, not dependent.
Ways to use us
Every one of these is run by the same senior engineers, so the person who designs the change is the person who answers when it misbehaves. Most co-managed clients use two or three.
Microsoft 365 and Azure migrations, server retirements, ERP and line-of-business rollouts, delivered to a scope and a date.
IT project delivery Toronto
24/7 monitoring, endpoint detection and response, phishing triage and incident handling, without your team watching screens at midnight.
Managed security for internal IT
Your team keeps business hours. We take the nights, weekends and statutory holidays, and leave notes for the morning.
After-hours IT coverage
Vacation, parental leave, a resignation, or simply a busy quarter. We plug into your queue and your process.
IT staff leave cover
Segmentation, firewall reviews, Wi-Fi surveys and switch replacements that need a specialist for a few days, not a hire.
Network and firewall escalation
Tenant design, licensing clean-up, identity and conditional access, and cloud cost control alongside your team.
Microsoft 365 escalation
Immutable copies, tested restores and a runbook your team can follow, with us on the line during a real recovery.
Backup and DR escalation
Budgets, roadmaps, hardware lifecycle and vendor negotiation reviewed with your IT lead every quarter.

Co-managed FAQ
If your question is not here, call 416-479-0505 and ask an engineer rather than a salesperson.
You keep your own IT staff and we add engineers where they need help — a project, specialist skills, leave cover or after-hours support. Your team stays in charge of your systems, and we agree in writing who owns what before any work starts.
