Zara's take · St. Catharines
St. Catharines is currently a balanced market.

There isn't enough monthly sales data yet for a 12-month price comparison. Supply is at ~6.0 months — between the usual seller's and buyer's thresholds.

Practical takeaway

Buyers: you have time to make a measured decision and negotiate. Sellers: presentation and pricing strategy matter more than timing.
