Why Gee Wizz

We're #1 in the #2 business.

Anyone can drop off a plastic box. We deliver a service: spotless units, a servicing schedule you can set your watch to, and a real person on the phone when plans change. That's why contractors across the GTHA keep us on speed dial.

  • MOL compliance, guaranteed. Every unit in our fleet meets Ministry of Labour requirements — inspectors welcome.
  • Cleaned like we use them ourselves. Pumped, scrubbed, sanitized and restocked on every scheduled visit.
  • Four-season reliability. Winterized units and cold-weather servicing keep your site running year-round.
  • Flexible terms. A weekend reno or a two-year build — daily, weekly and long-term rates.
“Units showed up on time, spotless every week, and when we extended the job by three months it took one phone call. Best porta-potty outfit we've dealt with, hands down — washed hands, obviously.”

Our Story

Owner-operated for over 25 years.

Gee Wizz isn't run from an office tower — it's run by Greg and Anthony Trentadue, who have spent more than 25 years on job sites across the GTHA. That's them in the photo, on a downtown Toronto high-rise build, doing the work themselves.

When the owners are the ones on the truck, things are different. Quotes are straight, units show up when promised, and if something needs fixing, the guy who answers the phone is the guy who fixes it. Twenty-five years of contractors calling back is the only marketing we've ever really needed.

  • Owner on every route — no call centers, no runaround
  • 25+ years serving GTHA job sites — we know your inspectors by name
  • Family business — our name is on every unit, literally

Good Questions

Frequently asked questions.

How often are units serviced?

Weekly servicing is standard and included with every rental — pumping, cleaning, sanitizing and restocking supplies. High-traffic sites can be scheduled for twice-weekly or more.

Are your units Ministry of Labour compliant?

Yes — 100% of our fleet complies with Ministry of Labour (MOL) requirements for Ontario job sites, including hand-cleansing facilities where required. If an inspector shows up, you're covered.

Do the units work in winter?

Absolutely. Our winterized self-contained units (single and double) are built for Ontario winters, and our whole fleet is winter-serviced with cold-rated products so nothing freezes up.

How fast can you deliver?

In most of our service area, next-business-day delivery is typical — and we can often do better. Call us for urgent needs and we'll shuffle a route.

How many units does my site need?

A common rule of thumb is one unit per 10 workers on a standard 40-hour week, serviced weekly. Tell us your headcount and schedule and we'll size it precisely — that's part of the free quote.

What areas do you serve?

The entire GTHA — from the Oakville–Burlington border across to Ajax, Whitby and Oshawa — plus north through Bradford and Innisfil to Barrie. Close to the edge? Ask; we're flexible.
