Dumpster Bin Rentals: What Size Should I Go With?

Renting a disposal bin is the most efficient way to clear out renovation debris, landscaping waste, or decades of garage clutter. However, a dumpster is not a magical black hole where everything can disappear.

Both municipal transfer stations and the Ontario Ministry of the Environment have strict regulations regarding waste disposal. Tossing the wrong item into your bin can lead to hefty contamination fees, environmental hazards, or a driver refusing to haul your load. Here is the definitive guide on what can and cannot go into your rental bin.

What CAN Go In Your Rental Bin

Fortunately, the vast majority of household junk and construction debris is perfectly safe and permitted in our dumpsters. We regularly accept mixed loads of the following:

What CANNOT Go In Your Rental Bin (Hazardous Waste)

Certain items pose a risk to the environment, the truck drivers, and the workers sorting the waste at the transfer station. Do not put any of the following items into your bin under any circumstances:

• Liquid Paint & Solvents: Empty, completely dried paint cans are okay, but wet paint, varnishes, thinners, and wood stains are highly flammable and toxic.
• Automotive Waste: Car batteries (lead-acid), motor oil, transmission fluid, antifreeze, and rubber vehicle tires. Tires require special recycling processing in Ontario.
• Freon Appliances: Refrigerators, freezers, and air conditioning units contain refrigerants that destroy the ozone layer. The Freon must be professionally drained before disposal.
• Toxic Chemicals: Household cleaners, pesticides, herbicides, pool chemicals, and bleach.
• Asbestos & Biohazards: Any materials containing asbestos (common in pre-1980s insulation and floor tiles) require specialized hazardous waste removal teams.
• Propane Tanks & Cylinders: Even if you think they are empty, compressed gas cylinders are an extreme explosion hazard when crushed at the dump.

Pro Tip: If you have hazardous materials, you must take them to a designated City of Toronto Household Hazardous Waste (HHW) depot. It is completely free for residents!

Rules for Heavy Materials (Dirt, Concrete, Brick)

While materials like concrete, brick, asphalt, and clean fill (soil) are allowed, they have very specific loading rules. These materials are incredibly dense. If you fill a standard mixed-waste bin to the top with concrete, the truck will physically not be able to lift it off your driveway, and it will exceed legal road weight limits.

If your project involves masonry or excavation, you must request a Heavy Materials Bin. These are specifically reinforced to handle dense loads and have strict fill lines that you must not pass.

Safety Rules for Loading Your Dumpster

Beyond knowing what to throw away, you must know how to load it safely:

1. Never Fill Above the Rim: By law, drivers must tarp the load before driving on public roads. If debris is piled above the top edges, the tarp cannot be secured, and the driver will refuse the pickup.
2. Distribute Weight Evenly: Do not put all your heavy demolition debris on one side and light cardboard on the other. An unbalanced bin is dangerous to lift and transport.
3. Load Heavy Items Flat: Place heavy, flat items (like drywall or doors) at the bottom to maximize space and maintain a low center of gravity.
