The Short Answer
What happens in Markham's fall real estate market in September? September marks the unofficial start of the fall market, when activity picks up sharply after the summer lull. Expect a wave of new listings and returning buyers early in the month, peak activity mid-month, and firming decisions toward month's end. It's one of the two busiest seasons of the year — and in 2026's tightening-but-balanced market, preparation and pricing matter more than ever.
Labour Day flips a switch in Markham real estate. After the quiet of August, families return from vacation, the school year begins, and the market wakes up for one of its most active stretches of the year. Michael John Lau, a top real estate agent in Markham, maps out what to expect from the fall market, week by week.
Why September Matters So Much
Real estate has clear seasons, and fall — kicked off in September — is traditionally one of the two strongest selling seasons of the year (alongside spring). The psychology is simple: summer distractions end, people refocus on major decisions, and both buyers and sellers who paused over the summer re-enter the market with purpose. Serious buyers want to be settled before the winter holidays, which creates a concentrated window of motivated activity.
The 2026 context: This fall arrives in a balanced market that has been tightening — as of July 2026, supply has been contracting (GTA new listings down notably year-over-year), well-priced Markham homes are selling in about a month, and the average Markham home sits around $1,131,000 (TRREB, July 2026). Fewer homes competing for steady buyer demand means well-prepared, well-priced listings are positioned to do well.
Week 1: The Post-Labour-Day Surge (Early September)
The market reawakens almost immediately after Labour Day. Sellers who prepared over the summer bring their homes to market, and the first wave of fresh inventory appears. Buyers who took the summer off return and begin actively searching in earnest. For sellers, launching early in this window means capturing that initial burst of pent-up buyer attention.
Week 2–3: Peak Activity (Mid-September)
The middle of the month is typically the busiest stretch. Inventory is building, buyer traffic is strong, showings and open houses are well-attended, and the market hits its fall stride. This is often the sweet spot — enough new listings to draw serious buyers, and enough motivated buyers to create genuine competition for the best homes. Well-priced, well-presented homes tend to see their strongest activity here.
Neeraj Moolchandani on Working the September Calendar
Neeraj Moolchandani, REALTOR® at Kaizen Real Estate, points out that the first post-Labour-Day wave competes against fewer listings for the same returning buyers, while the mid-September wave competes against everyone who had the same idea. Being early in a compressed window is generally worth more than being marginally more polished but late.
For buyers, Neeraj works the calendar in reverse. Listings that launch in the first wave and are still available four weeks later are frequently where a real conversation becomes possible in October. Buyers who track early inventory and revisit it once the initial competition clears often secure better terms than those competing directly in week one. Both approaches work. Drifting through September without one does not.
Week 3–4: Decisions Firm Up (Late September)
As the month progresses, the buyers who re-entered in early September have seen enough of the market to act. Offers and negotiations pick up, and decisions firm up. Buyers feel the pull of wanting to close and settle before the holiday season, which adds urgency. The homes that launched earlier in the month and were priced correctly are often the ones securing offers now.
Into October and Beyond
The fall momentum typically continues through October, often the peak of fall activity, before gradually easing toward the holidays. September sets the tone: it's when the season's inventory arrives and the season's buyers commit. Getting the early-fall timing right positions a home for the whole season.

How to Make the Fall Market Work for You
For sellers: preparation before Labour Day is what lets you launch into the early-September surge rather than scrambling. Correct pricing — especially important in a market where buyers have choice — plus strong presentation and marketing, positions your home to capture the season's concentrated demand.
For buyers: the wave of fresh September inventory means more choice than the summer offered. Being financially prepared — pre-approval in hand, criteria clear — lets you move decisively when the right home appears in the busy weeks.
Michael John Lau, one of Markham's leading REALTORS®, helps both sellers and buyers time the fall market well — preparing sellers to launch into the September surge and positioning buyers to act on the season's fresh inventory. Understanding the rhythm of the fall market is the first step to using it to your advantage. Every year is different, so let's build a plan around this one.
