I'm alone for Canada day and it's really not a big deal.
One good thing is that most restaurants have deals on Canada day weekend, so if I wanted to order out (and actually had money) it would be cheap.
I couldn't see any fireworks from the windows last night but I could hear them going off everywhere- which bothered me a bit, since it felt like the world was exploding.
I always feel completely and utterly alone, so it's not really a big deal if I'm alone on a holiday since it's just like every other day.
If you can go out, then go. If you don't want to, then don't. No sense in whining about it either way, though~ there's plenty of people in the world who have it worse.
