Read moreWhy choose us
Decades of trusted IT expertise.
With nearly four decades of experience, we have built lasting partnerships with businesses across Ontario. Here is why clients choose Computer Doctors On Call.
Experience
We have offered computer network repair and IT support since 1986, close to the beginning of the industry itself. That is four decades of situations, and very few of them are new to us any more.
Skill
We solve the immediate problem, but the services are designed to reduce your overall IT budget, deliver solutions built around your needs rather than ours, and connect a wide range of hardware and software into a secure, stable network.
Cost savings
Budget is always a concern. Our network solutions have delivered significant savings for clients over the years, and it is not uncommon for us to reduce overall IT costs by 25 to 50 percent.
Guarantees
We get IT done fast and done right. As we say, band-aid solutions are not enough. If you are not happy with the result, we do what it takes to make it right.

Computer Doctors On Call has served Ontario businesses since 1986. Our technicians arrive on site with the parts needed to complete the repair.
Jentu certified
Jentu diskless network management.
CDOC is a certified Jentu implementer. On a Jentu environment, workstations boot a central image over the network with no local hard drive and return to a clean state on every restart. We recommend it where it suits the site.

Our journey
From local IT help to trusted network experts
Since 1986, Computer Doctors On Call has grown from a small tech support service into a trusted name in network management and repair, serving businesses across Toronto, Vaughan, Mississauga and beyond.
Our mission
To provide fast, reliable and affordable network support that lets businesses operate without interruption, so every client gets the expertise of a full IT department without the overhead of one.
Our vision
To be recognised as Ontario’s most trusted partner for computer network repair and management, combining decades of experience, modern tools and customer first service.
Real support, real stories
Hundreds of satisfied customers.
For over 20 years, our clinic ran on custom servers by CDOC in one form or another. Since installation, the server has run flawlessly. Because the workstations do not require a hard drive, we have had no failures of our workstations, and no need to worry about viral attacks, hacking, drive crashes, operating system failures or weekly patching.
It is our pleasure to recommend Abraham Megidish and Computer Doctors On Call Ltd. to anyone that requires outstanding service and extremely knowledgeable and personable personnel. We highly recommend them for not only their expertise, but their outstanding service and tremendous savings.
Abraham came to our rescue when our business internet network failed our needs at a critical time. Not content with just getting us up and running again, he improved our existing system dramatically. Thanks to him we have avoided downtime and hours of hassle. My only regret is that we did not find him earlier.
