We flew into Toronto from Copenhagen and had a shortish connection with customs and whatnot. The directions as to where to go were "obscure" and we walked a long distance. The PA was informing us we had to wear masks but hardly anyone was doing it. The airport was dirty in general and had a lot of quasi-construction sites with no work happening. We finally asked a couple people and got directed, they said the signs were no help. We walked and walked and made out gate, if you could call it that, they had space for about ten people to sit with a 737 to ATL about to leave, except it wasn't. It was delayed, OK, we walked around some more, there were hardly any shops open anywhere near that "gate". It was like the back end of nowhere.
CDG has gotten a little better now departing. But arriving is a mess, from the US anyway. Delta seems to get the gate from hell.
