# Collecte MTL

Waste collection schedules for addresses in Montreal

Listed in ChatGPT

Overview

## What Collecte MTL does

Collecte MTL answers a narrow question: when waste is picked up at a given address on the island of Montreal. Entering an address returns the schedule for every stream at that location: household garbage, recycling, organic and food scraps, yard and garden waste, and large items, along with the next dates due in that sector.

It also locates the closest ecocentres for materials that are not collected at the curb, and reports the borough's waste recovery and diversion rates.

The source is the City of Montreal's Secteurs Info-collectes open data, updated roughly once a month. The tool is free and independent, with no affiliation to the city. It holds no personal information, and an address serves only to identify which collection sector it falls in.

### Who it is for

Residents of Montreal checking pickup days for a specific address.

### What stands out

It draws directly on the city's official open data and stores nothing about the address entered.

## Where Collecte MTL is listed

Collecte MTL is listed in the ChatGPT apps directory only. Sebastien Castiel has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
