The Short Answer
What's happening with Unionville GO Station parking? Due to construction for the Ontario Honda Dealers Indy at Markham race, roughly 300 parking spaces at the south end of Unionville GO Station — plus the east overflow lot and east access road — are temporarily closed until around mid-December. The main parking lot remains open, and about 180 overflow spaces are available at the nearby Pan Am Centre (a 5-minute walk). Commuters should plan ahead and arrive early.
If you commute from Unionville GO, or you're considering a home near it, there's a temporary disruption worth knowing about — and it's tied to one of the most exciting things happening in Markham. Michael John Lau, a top real estate agent in Markham, explains what's going on and what it means.
What's Closed, and Why
Metrolinx (which operates GO Transit) has temporarily closed parking at Unionville GO Station to accommodate construction for the infrastructure supporting the new Ontario Honda Dealers Indy at Markham — the IndyCar race coming to Downtown Markham in August 2026. The temporary race circuit runs partially on the Unionville GO property, so preparation work affects the station.
The specifics (as reported): Approximately 300 parking spaces at the south end of the station's parking lot are closed, along with the east overflow lot and east access road, until around mid-December. The main parking lot remains open. Roughly 180 overflow spaces (including accessible spaces) are available at the Pan Am Centre, about a 5-minute walk from the platform. Details and timelines can change — always check GO Transit's Unionville construction notices for current information before you travel.
What Commuters Should Do
Plan ahead and arrive early
With reduced parking, spaces can fill faster. Metrolinx advises commuters to plan ahead, arrive early, and follow directional signs near the construction areas.
Use the Pan Am Centre overflow lot
About 180 overflow spaces are available at the Pan Am Centre, a short 5-minute walk to the train platform. Access is via Main Street Unionville (from Unionville Gate via Kennedy Road); exit via the south access road onto YMCA Boulevard.
Use the main access on YMCA Boulevard
Metrolinx advises entering and exiting Unionville GO through the main access on YMCA Boulevard during construction.
Consider alternatives
Reserved parking users are being contacted directly. Some may consider carpooling, being dropped off, or nearby GO stations during the construction period. It's temporary — normal parking is expected to be restored after the work.
Neeraj Moolchandani on Temporary Disruption and Permanent Value
Neeraj Moolchandani, REALTOR® at Kaizen Real Estate, watches how buyers react to news like this as a useful indicator of their own horizon. A temporary parking reduction that resolves in a few months should not move a decision about a home someone intends to own for a decade. When it does, that usually reveals the buyer was uncertain about the purchase for other reasons.
The genuine takeaway Neeraj draws is about walkability rather than parking. Buyers who can walk to Unionville GO are insulated from parking capacity entirely, now and in future, and station lots across the network get tighter as ridership grows rather than looser. That is a structural argument for paying attention to walking distance, and this closure is a short-term illustration of a long-term point.
What It Means for Buyers Near Unionville GO
Here's the perspective that matters for anyone considering a home near the station: this is a temporary disruption tied to a permanent positive. Two things are worth understanding:
The inconvenience is short-term
The parking reduction is a temporary construction measure, not a permanent change. Normal station operations and parking are expected to return once the work is complete. A short-term construction phase shouldn't drive a long-term home decision.
The Indy is a long-term positive for the area
The reason for the disruption — the arrival of a major international motorsports event in Downtown Markham — is a significant, ongoing boost to the area's profile and economy. The five-year Indy commitment brings visitors, spending, and international attention to Downtown Markham, supporting the long-term appeal of the surrounding area. In that light, the temporary parking shuffle is a small, short-term cost of a meaningful long-term gain.
Unionville GO remains a premium transit asset
Beyond the Indy, Unionville GO is a major transit asset with ongoing GO Expansion improvements bringing more frequent, all-day service. Proximity to it remains a genuine long-term value driver for homes in the area — construction phase notwithstanding.

The Bottom Line
If you commute from Unionville GO, plan ahead through mid-December and use the Pan Am overflow lot. If you're considering a home near the station, don't let a temporary construction disruption cloud the picture — the area's transit access and the economic momentum behind the disruption are both long-term positives. As always, check current GO Transit notices for the latest details.
