Accessing old bus route schedules

Hi there,

This might seem like a really niche thing to ask but anyways: is it all possible to access past bus route schedules for the MiWay somewhere online?

For context, my bus stop seems to have changed in schedule to around 10 minutes earlier than its usual time. I looked on Mississauga’s website for any service updates for my bus route and there weren’t any which got me curious.

I know it might be easier to ask this question to the city through e-mail for example but I wanted to know if this alternative (of some sort of historical file for bus schedules) is possible.
