My understanding is that the TH in Camada have donuts shipped to them from. Central location rather than baking those on premises. Could be out of date info though, I don't know. I've wanted to try Tim Hortons just because it's a central Canadian think in a webcomic I once read (Avalon) but I have never succumbed to the idea of an insane weekend road trip to canada to try a donut. I do hope they come to the US near me.
Honestly, the donuts or the coffee aren't worth the drive. Canadian's love it for the nostalgia, not because it tastes amazing.
As a kid you went there with your parents. As a teen you went there with your friends. In highschool/summer, when you didn't have specific plans (@4pm or @4am), you met up at TH. In university, you'd go get a soup, sandwich and drink, sick of eating the same thing for the 4th time this week. Now as an adult you go back home, and if you're meeting old friends, you know you're meeting at Timmy's. Infact, half the fun is meeting at Timmy's. I think I'm quoting one of their ads but, for Canadian's "Its [just] where life happens".
Anyways, not saying you shouldn't take the road trip. Long drives with a friend or two just for some "mediocre" food are the most fun trips. I have one almost annually for In-N-Out. Definitely don't be expecting ambrosia though, its awesome because its not special, its just a donut and a double double.
I once drove four hours to the closest Krispy Kreme in my area the day it opened. It was worth every second of driving just to eat them. I brought back 10 dozen donuts and sold them locally for double the price.
Now living in Canada, I would probably drive 10 minutes to a Timmy's, but that's about the extent of it. The donuts aren't as good as the other local donut franchise (Robin's), and their coffee is absolutely terrible. Krispy Kreme is superior in every way.
If you find yourself in Canada, stop in and buy a Double-double and some Timbits. Don't make going to Timmy's the point of a trip.
