It would appear that the Air Canada Timetable PDFs were finally removed in the last few days.
The former link: https://services.aircanada.com/porta...metable-en.pdf
And for fun, the Wayback machine for a version of the timetable from 2011: https://web.archive.org/web/20111125...metable-en.pdf

Maybe I'm just stuck in my older ways of doing things, but even in 2024 I still preferred looking at the PDF to using various online tools. Sad to see it go.... hopefully it resurfaces somewhere else.
