Don't know what it is but I'm in Montreal for a month and the city is absolutely amazing. I've been to Seattle, Portland, SF, LA, Vancouver and I like Montreal WAY more. Super interesting and beautiful city. Very relaxed and welcoming with tons of stuff to see and do. It's also pretty cheap too.
I HIGHLY reccomend going.
EDIT fuck im and idiot I didn't make the connection that fierte Montreal would main GAY pride and not just pride in general. And yeah the city is already so gay I don't know if I could handle it any gayer.
