What it does

Ontario's catalogue provides public data with ministry, group and developer-resource routes.

Choose the ministry or topic, then check Access Level before planning a download: Restricted records remain listed but do not share the data, and Under review is undecided. The About guide explains file URLs, machine-readable formats and dictionaries, plus the difference between validation, file-update and catalogue dates. Follow any resource-specific access instructions and licence rather than assume every listed record is downloadable.

Strengths

Guidance distinguishes open, under-review and restricted records
Documented file formats, dictionaries and metadata date meanings

How the SI Score works →

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.

Sources and checks

Supporting pages for product usefulness, site facts, prices and separate website checks. Each record keeps its own date. Reading a page does not establish how well the product performs in use.
