We bring the discipline of large-scale project management — real planning, budgets and schedules — to renovations and builds across Hamilton and the GTA.
Book a free consultationJopie Construction Group traces back to 2016, when founder Johnpaul Guminkiriza began his construction career in Africa, going on to lead infrastructure projects valued over $100 million as a member of the Project Management Institute (PMI). After relocating to Canada, he registered Jopie Construction Group in Ontario in 2026 — bringing a decade of hands-on, major-project discipline to homeowners and businesses in Hamilton and the GTA from day one.
We're a new company in Ontario, built on experience that isn't new at all. Too many construction projects go over budget and past deadline because no one is truly managing them. We run every job — large or small — with the same planning rigour as a multi-million-dollar build.
Today we're a general construction contractor serving Hamilton and the Greater Toronto Area, handling complete projects from planning through to the final finishes. We self-perform many of the trades in-house — drywall, painting, tiling, flooring and more — and manage the rest, so our clients deal with one accountable team instead of juggling subcontractors.
Johnpaul's construction career started in Africa in 2016 and grew into leading infrastructure projects valued over $100 million. He's a member of the Project Management Institute (PMI) — a global, not-for-profit professional organization dedicated to standardizing, expanding and certifying the practice of project management. He's hands-on with every Jopie project, from the first walkthrough to final sign-off — not a name on a website.
What sets Jopie apart is the experience leading the company. Johnpaul is a PMI-member project manager with over 10 years managing major infrastructure projects, including projects valued over $100 million. Planning multi-million-dollar builds means living and breathing scope, schedule, budget, risk and coordination — and that's exactly the rigour brought to your renovation or commercial project.
For you, that means honest estimates, realistic timelines, tight coordination between trades, and a single point of contact who actually keeps the project on track.
WSIB-certified and fully insured, with site safety managed to professional standards on every job.
Proper preparation and workmanship, backed by a workmanship warranty — we stand behind what we build.
Realistic schedules and active management so your project finishes on time and on budget.
We work with homeowners, property managers, developers and commercial clients across Hamilton, Burlington, Oakville, Mississauga and the wider GTA — on residential, commercial and industrial projects of every size.
