A century of experience

A future of innovation

GDI's Story Begins

Robertson Janitorial Ltd. began as a small, reliable cleaning service supporting Quebec City’s growing economic landscape. With a focus on consistency and care, the company steadily grew. 

Ainsworth is Founded

Brothers F.C. and C.J. Ainsworth establish an electrical services company that grows into a technical services leader.  

Two Leaders Join Forces

GDI acquires Ainsworth, bringing facility and technical services together in one North American organization.

Celebrating 100 Years

GDI and Ainsworth are uniting under the name GDI Ainsworth: one company, one culture, and one vision for the future.
