How we update

groups of official and public sources feed the site. Every morning a routine downloads each source, checks it and saves it. Every block on the site shows underneath where it came from and when it was updated (“Source … · updated …”).

“Behind schedule” means a source's last good load is older than its frequency. It happens when an official site is down or changes its format: the update stops and flags it instead of saving wrong data.

How the routine works

The routine runs by itself on GitHub Actions, one source after another. Times are in UTC, with Ottawa time alongside.

Every day at 09:30 UTC (4:30 or 5:30 a.m. in Ottawa):
House of Commons, Senate, the legislatures, Quebec's municipal directory, the NWT communities and the city websites, then photos and earlier roles for anyone new, then the coverage report.
By hand, when it changes:
the Yukon Legislative Assembly, whose site blocks automated reading. A copy of the page is saved in a browser and loaded from there.
When boundaries change:
the map shapes, rebuilt from Natural Earth.

When a download fails, it is tried again up to three times (six for the NWT site, which is often slow). If a source still fails, or suddenly returns far fewer people than the day before (under 90%), its update stops and the run is marked as failed. The site keeps the previous data, with its date, until the next good read. Someone leaves office on the site only after missing from their source two days in a row, and nothing is deleted. The raw files from every run are kept for 90 days, so any number can be traced back to what the source published.

Every source and its licence

Each source with a link to the page we read, its terms of use, and its last good load.
