From the blogto article linked by op:
He says that "After a couple of sips, it became soggy and started to stain. Thereafter, I could taste a few small lid pieces in the drink, which was like 'yuck.'"
Yep sounds like terrible design and Tim's cheapen out in the material. I've had non plastic caps that were much better than that.
You know what would bring us back to the good old days? A real ceramic mug you can use to sit down, drink it slowly and enjoy. But I haven't been to a Tim's in a while where the server would ask if I wanted a mug or to go. Maybe the lady would call that woke too?
I don't think it's fair to look at Canada as a monolith. Quebec is generating most of its energy from hydro, whereas Ontario relies on a well established nuclear energy infrastructure. Provinces that need to change are Saskatchewan, Manitoba and Alberta.
Edit: Manitoba actually relies on hydro for 97% of their usage. So correction: only Alberta and Saskatchewan!
