Slip out of Toronto for a last-minute solo weekend in Quebec City: three September nights in a walkable UNESCO old town of stone walls, the Château Frontenac skyline, and Petit Champlain’s cobbles, with early-fall light on Dufferin Terrace and the St. Lawrence. Keep the plan loose—café au lait, French-Canadian plates, a Plains of Abraham stroll, and unhurried wandering through Vieux-Québec—so the escape stays compact, atmospheric, and easy to enjoy without a packed itinerary.
Round-trip Toronto–Quebec City air is the fastest fit for this 3-night solo weekend (~90 minutes vs a full day by car or train). No live fares are loaded and transportation is budgeted at $0, so flights sit outside the current $1,100 plan.
