We're already halfway through September! Soon, we'll be saying goodbye to Montreal's rooftop terrasses and urban beaches and hello to fall hikes and pumpkin spice chai lattes.No matter the season, the 514 always has a lot to offer for weekend enjoyment.On the horizon this weekend are a techno party, a vintage clothing sale, free dance lessons, a farmers' market and even a tattoo convention.So, which one of these events is calling your name?
