About

Founded by Paulo Santos, PCMac.tech is built on more than two decades of hands‑on experience in the technology industry. Paulo began his career in 1998, working through the rapid transformations that shaped modern computing. In 2014, he launched Tek‑on‑Site in Ottawa as a dedicated computer repair service focused on fast, reliable onsite support.

As technology evolved, so did the company.

Today, Tek‑on‑Site continues to operate as the backbone of our services, now proudly delivering solutions under the PCMac.tech brand. This shift reflects the new reality of the tech landscape—where cloud platforms, mobile workforces, and connected environments have become the standard for both homes and small businesses.

What began as a computer repair service has grown into a comprehensive technology partner. We now provide:

• Network cabling and infrastructure

• Secure Wi‑Fi design and deployment

• VoIP phone systems

• Cloud solutions including Microsoft 365 and Google Workspace

• Backup and data protection services

• Onsite and remote tech support for computers, networks, and devices

Our mission is simple: deliver dependable, modern, and personalized technology solutions that keep your home office or small business running smoothly.

Whether you need hands‑on support at your location or remote assistance from anywhere, PCMac.tech is here to make technology work for you.
