It would appear that the Air Canada Timetable PDFs were finally removed in the last few days.
The former link:

And for fun, the Wayback machine for a version of the timetable from 2011:

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.
