10, 20 and 40 Cubic Yard
Dumpster Rental in Mont-Saint-Grégoire

Not for the dumpster itself, if it sits entirely on your land. We word it carefully because the conclusion comes from an absence of provision: the list of work requiring a certificate of authorization runs to 22 entries in by-law 2009-188 and none covers a temporary dumpster — entry 19 covers permanent occupancy of the public road right-of-way. The same by-law's fee schedule charges nothing of the kind, and neither does by-law 2024-303 on municipal service fees. The job site, however, often does need a certificate: “repair or renovate a construction” is covered, and the only maintenance exemption is minor repairs with no change to the structure whose value does not exceed $2,500. In doubt? The municipal and building inspector answers at 450 347-5376, extension 26, or at permis@mmsg.ca.

Yes, and it is written in plain terms. Section 8.5 of construction by-law 2009-187, headed “Conteneur à rebuts”, provides that “throughout the period of construction, alteration or demolition, the person responsible for the work must have a container installed on the lot to collect construction or demolition debris”. Three points that matter: the duty falls on “the person responsible for the work”, so the contractor as much as the homeowner doing it themselves; it covers construction, alteration or demolition, not a simple basement clear-out; and it says “on the lot”, not on the street. Section 8.4 completes it by prohibiting the burning of those materials. In Mont-Saint-Grégoire the dumpster is therefore not a convenience: it is what makes a job site compliant.

Not without written authorization. Construction by-law 2009-187 is explicit: “No one may use a public street in connection with work without first obtaining written authorization from the municipal inspector”, and that authorization imposes at most one third of the road width, trestle or barrier marking by day, lights approved by the inspector at night, sidewalks clear at all times, a full clean-up within two weeks and a liability insurance policy kept in force for the whole occupancy. Leaving construction materials on public property is also a prohibited nuisance, and obstructing traffic in a public place without valid reason is an offence. Two draft by-laws naming “conteneurs” are slated for adoption on September 8, 2026, but they are not in force as of August 20, 2026: we do not present them as law. So the spot is on your land — that is where we deliver, and where the by-law wants the dumpster.

It is the question specific to Mont-Saint-Grégoire, and the one to raise on the phone. By-law 2023-295 caps the clear length of a private driveway culvert at 6 metres (8 m for a commercial entrance, 11 m industrial or agricultural), requires a pipe of at least 450 mm (18 in.) approved by a municipal representative before installation, bars it within 15 m of an intersection, and demands a crossing “stable and durable, offering sufficient resistance to applied loads”. Section 9 adds that damage to municipal infrastructure caused by a non-compliant culvert is the owner's responsibility, with the municipality able to recover the cost “as a property tax on the immovable concerned”. A loaded dumpster weighs several tonnes: tell us the age and condition of the culvert and we will choose the drop angle accordingly. Same reflex for the well and the septic field, since there is no drinking-water treatment plant on the territory and the sanitary sewer does not serve every property in the village core.

For a car trunk, yes. For a job site, no — and you have to drive first, because there is no drop-off centre on the territory: Compo-Haut-Richelieu's four sites are in Saint-Jean-sur-Richelieu, Lacolle and Saint-Rémi. Each address gets 3 free visits of 75 cu. ft. per calendar year; concrete, asphalt, brick and stone are capped at 75 cu. ft. per load and refused at the Saint-Rémi site; sand, soil and peat are refused for every user; “use of the tipping mechanism is prohibited” and so are dump trucks with 6 wheels or more. The arithmetic is quick: a 10 yard dumpster holds 270 cu. ft., more than an address's entire annual free allowance (3 × 75 cu. ft. = 225 cu. ft.); a 20 yard holds 540 cu. ft. and a 40 yard 1,080 cu. ft. Add that both the garbage bin and the monthly bulky waste collection refuse construction materials.

Two by-laws in force give two answers, and we publish the one that satisfies both: 7 a.m. to 9 p.m. By-law 2021-281 on nuisances, the more recent, defines “Night” as 9 p.m. to 7 a.m. and makes construction, renovation or repair work carried out at night a nuisance, while stating that site work carried out by day is not one. By-law 2017-254 (RM-420) on noise sets the window at 11 p.m. to 7 a.m. No by-law found imposes a tighter schedule on Saturdays, Sundays or holidays — but an absence is not a permission, and neighbours remain protected by the general nuisance regime. Both texts expressly exempt agricultural activity in an agricultural zone — the noise by-law being the only one to add “under the Act respecting the preservation of agricultural land and agricultural activities”.

In the driveway, and the room is reserved along with the date. From November 15 to April 1 inclusive, overnight parking is prohibited on the municipality's public roads: by-law 2019-271 says “between midnight and seven in the morning”, by-law 2017-252 (RM-330) says “between 11 p.m. and 7 a.m.”, and the municipality's “Déneigement” page publishes the 11 p.m. version. The fine is $30 under both, and a peace officer may have a vehicle moved at the owner's expense during snow removal. In the driveway, the dumpster shares the room with the temporary car shelter — allowed from October 15 to April 15, one per lot, with a front setback of at least two metres — and with the snow, which may not be disposed of in the ditches or in streets belonging to the municipality. A Mont-Saint-Grégoire driveway is at most 6 m wide: that is why we talk about it when you book.
