Should be a good time. many locals will be tied up with family, travel, etc.
Just to be sure, call ahead to your providers of choice to make sure they'll be open.
Nueromag! Its a great week end to be in Montréal, but less so for hobbying. It won't be totally deserted, but a lot of the girls will go away on the week end, especially that it's a long week end. It's a party week end for people with their friends or families... If it rains though some may stay in town to work, but otherwise...
Yep do the math !
Since July 1st is also a holiday...
For anyone on payroll who takes 4 days vacation (27,28,29,30) they get a vacation from June 24th to July 3rd. That's a 10 days straight out of only 4 days taken from their holidays.
This is one reason why a lota people go on vacation that week in Quebec... or move !
