Ontario's scene is top-heavy in the best way: the Agawa Canyon Tour Train is one of the great scenic rides in North America, a 114-mile run into a canyon you cannot reach by road, at its peak in the fall colour season.
South of it, a healthy heritage cluster — South Simcoe, Waterloo Central, Halton County's streetcars, Port Stanley, Huntsville's Portage Flyer and Smiths Falls' caboose rides — covers most weekends from spring to Christmas. Be aware that two famous names are gone: the York-Durham Heritage Railway and the Credit Valley Explorer have closed, whatever older listicles still say. That is exactly why this list is re-checked every year.
How many listings typically run in each month — patterns, not schedules.
Scenic excursion trainOperating
Sault Ste. Marie, ON
SeasonAug-Oct (2026: Aug 1-Oct 18)
Ontario's flagship train ride: 114 miles north from Sault Ste. Marie into the roadless Agawa Canyon, with time in the canyon park for waterfalls and lookout trails. It runs from late summer through the fall colour season, when it is at its best — and busiest.

⚠ Check before you travel: the operator's own pages and booking calendar don't fully agree — the homepage's headline fare doesn't match the booking calendar's date-by-date fares, the season's closing date appears as two different dates in operator material, and the canyon stop is given as both 90 minutes and two hours. Confirm the fare, the date and the stop length on the booking page for your day.
Heritage streetcar museumOperating
Milton, ON
SeasonMay-Oct weekends/holidays, Thu-Mon Jul-Aug; early Dec Christmas on the Rails

⚠ Planning a late-season visit? The museum's own website disagrees with itself about November — one page says closed for the month, another says open weekends until November 1. Confirm before you go.
