Monthly Lobbyist Communications With Canadian Public Office Holders

Canadian federal data discloses oral and arranged communications between lobbyists and Designated Public Office Holders. Reports are filed monthly with the Office of the Commissioner of Lobbying under the Lobbying Act, which came into force on July 2, 2008. The dataset includes primary and secondary CSV files to handle one-to-many relationships for some data elements.

Strengths

• Data is provided with a supporting data dictionary file defining all data elements.
• Includes both primary and secondary files in CSV format to accurately represent one-to-many data relationships.
• Sourced from the authoritative Office of the Commissioner of Lobbying of Canada, the official regulator.

Limitations

• Row count and specific column names are unknown, limiting precise assessment of dataset scale and structure.
• Content is entered manually in the language of the user's choice, which may introduce inconsistencies in multilingual text fields.
