Stratford Railway Station (XFD) is a train station in Stratford, Ontario, not an airport, so it has no aviation lounge of any kind, and anyone searching for one here is really asking about a rail stop rather than an airfield. The station serves passengers connecting to and from the wider VIA Rail network rather than offering anything resembling an airline lounge.
Stratford itself is best known as the home of the Stratford Festival, the real and long-running Shakespearean theatre festival that draws visitors from across Ontario and beyond each season, and the railway station exists largely to move that theatre-going traffic along with regular commuters and regional travelers. Waiting at Stratford means a modest station building with basic seating rather than a members-only space of any description.
For an actual airport lounge experience connected to this part of Ontario, Toronto Pearson International Airport is the realistic reference point. Pearson hosts a genuine lounge landscape, including Air Canada's Maple Leaf Lounges and independent Plaza Premium locations, available through airline status, elite programs, and paid access in a way that a regional rail station like Stratford never could. Travelers heading to Stratford for the Festival or for business typically fly into Pearson first and then continue on by road or rail to reach the town itself.
The Stratford Festival season, which runs roughly from April through late October, is when Stratford's own train and road links see the heaviest travel, so if your trip is timed around a performance, expect busier trains and fuller parking rather than any lounge-related crowding at the station itself. Plan your real lounge stop at Pearson if your itinerary includes a flight, confirm current Air Canada or Plaza Premium access with your airline or card program before you travel, and treat the Stratford stop itself as a simple, functional rail connection rather than a place to look for lounge amenities.
