What the numbers mean

• Owners valued the median home at $669K in the 2021 census. Indexed to September 2026 prices with the Montréal CMA MLS® Home Price Index (+22% since then), that is about $818K, 34% above the Montréal median of $611K. It is an estimate: the index tracks the whole region, not this neighbourhood.
• 70% of households rent, above the 64% city-wide, so expect a younger, more mobile mix of neighbours.
• Only 8% of residents are under 15, versus 15% city-wide.
• 42% of residents are 20 to 34, versus 24% city-wide. It skews young-professional.
• 88% of homes are apartments (73% city-wide), so a condo is the usual way in.

• Reported crime has risen since 2020 (224 to 430 incidents a year).
