I can't speak for Cannon, but while there were some lifts where the lines were much longer, this was the exception, rather than the norm. The extra spacing made lines look longer than they really were, and if the queue was full to the same amount, you probably waited the same amount of time.
I'm going to use Killington's bubble chair as an example. It has a front row style queue with a staff member up front directing people when to come out. In normal times, there were 6 lines for groups, plus two singles lines. This year, they had the same 6 group lines with spacing between, but only 1 singles line.
In normal times, if there were repeated 2's and 3's, they'd move up and make their own larger groups. This year, they stayed apart as their own groups. If the line was back to the end of the queue, there were the same number of groups in front of you as there would've been in previous years. It's just that those groups were smaller. The waiting time however would've been the same.
I noticed that gondolas, and lifts that function as overflow to gondolas tended to have the biggest increase in waiting times. This was due to the fact that gondola capacity was so extremely limited with cabins built for 8 sometimes going up with just 1, making the lines longer. People would seek the alternate lift either because the line was too long, or because they didn't want to take the gondola at all due to covid concerns. The most extreme case of this was Gore's Adirondack Express, but there were certainly others.
