About 5ième Avenue 5ième Avenue was founded in Montreal, and we love our city. We believe in keeping close to our roots and as such, have been making waves in the Montreal menswear community since 1975. Its hard for us to pin down one specific attribute to describe who we are or how we operate. We can’t really be described in one or two simple words. Simply put, we are what every man needs. We know that shopping as a man can be difficult.
