Sub-markets of the Metro Montreal area have fewer monthly transactions and this means that a small number of home sales can have an oversized influence on the reported statistics. We always recommend buyers and sellers watch both the local market and the regional Metro Montreal Report. A sub-market can outperform (or underperform) the region but the saying "a rising tide floats all ships" applies to real estate too. A sub-market can't trend differently from the region for very long.
