A weather backup should be geographically close to the original plan so the day does not collapse into cross-city travel.
Waterfront backup
Use the aquarium, indoor attractions or Union-area spaces instead of a long island visit.
Museum corridor
ROM, AGO and smaller museums can anchor several hours. Check timed tickets before assuming same-day admission.
Markets and indoor streets
St. Lawrence Market, PATH sections and covered shopping can help, but they are not all continuous tourist attractions.
Severe weather
Follow official alerts. Do not continue exposed waterfront, island or park plans during lightning, extreme heat or dangerous wind.
