Data & Methodology

Sources

  • Lobbying registrations and communications — Office of the Commissioner of Lobbying of Canada.
  • Speeches, bills, votes, and MP rosters — OpenParliament.ca and the House of Commons.

How often it updates

Data is refreshed weekly from the public sources above. Each page shows the most recent activity we have on record. Government sources publish on their own schedules, so there can be a lag between when something happens and when it appears here.

Known gaps

When Parliament is dissolved (for example, ahead of a general election) or adjourned between sittings, there are no new speeches, bills, or votes until the House sits again. Lobbying communications continue to be filed during these periods.

Grades

The letter grade on the rankings pages is a 0–100 score converted to a letter on a fixed scale. The score blends three percentile comparisons against all other MPs: how often the MP speaks in the House (50% of the score), how many different policy areas their recorded activity touches (25%), and lobbying exposure (25%) — where lower, less concentrated attention from lobbyists scores higher.

So an A+ means a score of 95 or better — an MP near the top of the speech and policy-breadth percentiles with low lobbying concentration. The full scale: A+ (95+), A (87+), A− (80+), B+ (73+), B (67+), B− (60+), C+ (53+), C (47+), C− (40+), D+ (30+), D (20+), F (below 20). Because the inputs are percentiles, grades are relative — they compare MPs to each other, not to a fixed standard, and they measure recorded activity, not the quality, character, or ideology of an MP's politics.

Organization pages

Organization pages show MP-directed lobbying communications filed in the registry. Organizations are identified by their registry name and appear on their own page if they have had 5 or more recorded meetings with MPs since January 2024. Meeting descriptions — what the lobbyist asked for — are filed by the registrants and have been available in the registry since mid-2024.

Corrections

All data originates from public government records. If you spot an error, it is most likely in the source data — but tell us and we will look into it.
