This was yet another Monday puzzle I got through quickly but got something wrong. I spent more than equal time finding that one square as completing the rest of the grid. And when I found it, I was not only annoyed but educated.

The clue I decided to pull out today is 14A Suffix with switch: EROO.

This is the one that turned out to have given me so much trouble. I went through the entire puzzle over and over to try to find anything wrong at all. I started to feel like the puzzle was broken and just didn’t recognize my accurate completion. There couldn’t be an issue with AROO.

But there was. 1D ___ and haw: HEM makes way more sense than does HAM. So that’s that.

I figured out the theme on the second related clue.

I skipped 8A Capital of 71-Across because I hadn’t gotten to 71A.

18A *Restaurant chain known for its coffee and doughnuts had the right number of spaces for TIMHORTONS, so I quickly jumped back to 8A.

8A Capital of 71-Across: OTTAWA–whose hockey team is appropriately named the Senators.
18A *Restaurant chain known for its coffee and doughnuts: TIMHORTONS
62A *Pancake topping: MAPLESYRUP
4D *Leafs-watching time, maybe: HOCKEYNIGHT, though I had thought and then rejected HOCKEYFIGHT for the Toronto Maple Leafs clue.
27D *Important step after erring: SAYINGSORRY, even though I would have expected it to be SAYINGSOREY.

71A Place associated with the answers to the starred clues: CANADA, of course!

Completion time was an appalling 12:41, but at least now I know it’s SWITCHEROO and not SWITCHAROO. And knowing is half the battle.
