Thirsty City Self Guided Tours

Sunday June 19, 2016, 2 PM - The Laurentian Channel: A Long Lost River. We will explore the origin, course and significance of one of the remaining ancient rivers in southern Ontario, which continues to flow today. Deep underground, it links Georgian Bay to Lake Ontario, passing under High Park. Its waters were unexpectedly brought to the surface by city workers in 2003, and tell the story of its source and significance. A linear walk, approximately 2 km, along some city streets, but mostly on paths within High Park, ending near Spring Creek on the east side of the park, within an easy walk of the Howard Park streetcar loop. Moderate difficulty; some slopes and mud paths; please wear appropriate footwear. Washroom access in High Park. Meet at the southwest corner of Bloor Street W. and Indian Road (2 blocks east of Keele St.). Leaders: Helen Mills, Bill Clarke and Paul Overy.

Sunday, July 17, 2016, 2 pm – What’s in a Name? Historic Meadow Creek. Meet at Lawrence Ave. W. and Duval Dr. (east of Keele at the north side TTC stop) for a linear walk along a live tributary to Black Creek ending at Rustic Drive, east of Keele. The stream’s ravine holds secrets of the urban wild and wears the many names this relatively unknown creek has been assigned over the years. Paved park trails with washrooms at the rallying point. Leaders: Ian Wheal, Helen Mills, John Wilson.

Saturday August 6, 2016, 1-3 pm - High Park Poetry Walk Meet at High Park Nature Centre @ the Forest School, 375 Colborne Lodge Drive, Rain or shine, Free. Join Jon Hayes, Program Supervisor, High Park Nature Centre, Helen Mills of Lost Rivers, John Wilson, former chair of the Task Force to Bring back the Don, and poets Maureen Scott Harris, Maureen Hynes, Dilys Leman and Nicholas Power for a poetry walk! Hear poems inspired by the Park’s black oak savannah, the serpentine wanderings of buried creeks and the dramatic 2003 discovery of the aquifer whose source was buried 10,000 years ago, as well as the plants, birds, snakes and insects that make their home in the Park. And – the poets promise to feature treasures from the Nature Centre’s “word of the week!” (

Moderate difficulty; some slopes and mud paths; please wear appropriate footwear. Washroom access in High Park.

Sunday, August 21, 2016, 2 pm – A Late Summer Tour of the Rouge Park. Parks Canada staff will join Lost Rivers walk leaders to hike Little Rouge Creek, a river whose course from the headwaters on Oak Ridges Moraine is the least developed of GTA rivers. A circular 4.5 km hike on unpaved park trails starting and ending at Twyn Rivers parking lot, located on Twyn Rivers Dr. 1.5 km. east of Sheppard (after the second bridge). Carpooling is recommended, as the parking lot gets full, and the nearest bus stop is at the Sheppard-Twyn Rivers intersection. Rest rooms available at the walk’s mid-point at the Rouge Park Welcome Centre.

Sunday August 28, 2016, 2 PM - Food, Water and the Evolution of Dinner. Explore the evolving past, present and possible future relationship between water and food in the area of the headwaters of Lost Garrison Creek. Rediscover the fundamental role of water in food production, learn something about the water footprint of the food we eat, and make some surprising connections with local lost rivers. Along the way we will be walking through a neighbourhood that was once a giant orchard, and discovering that many fruit trees still grow here now. A linear walk, approximately 2.5 km, mostly along city streets, ending near St Clair and Winona. Minimal difficulty, with few slopes or paths. Washroom access at Wychwood Barns. Meet at the Christie Street entrance to the Wychwood Artscape Barns, 601 Christie Street. Leaders: Helen Mills and Paul Overy.

Sunday, September 18, 2016, 2 pm – Taylor’s Todmorden Mills at the Don River Fall Line. This walk will search for lost manufactured watercourses – the mill races of the Lower (Todmorden) Mills and Middle Mill, along with other hidden remains of the industrial heritage that shaped the Don River Valley. Meet at Todmorden Mills Museum (67 Pottery Road, just west of Broadview) for a linear walk ending at Beechwood Drive and Broadview. John Wilson, Don River advocate, will lead with help from friends. Public washrooms available at the starting location only. TTC access on Broadview. Paved trails with some uneven ground

Sunday, October 16, 2016, 2 pm – Gerrard Prairie: Still Intact, but How Long? Three years ago we toured this remnant prairie on the Birch Cliff Quarry lands, scheduled for redevelopment over years of community objection. We’ll see what’s left of wild nature and learn what’s threatened. We’ll learn how this uncommon ecosystem formed and how it has survived cycles of use and neglect. Richard Anderson and John Wilson co-lead. Meet in front of Victoria Park station for a circular walk that includes some uneven, rough ground. Washrooms only available in businesses enroute.

Plans for walks are constantly being developed. We welcome your suggestions for interesting walks. Maybe you might like to lead a walk. Send your suggestion to: The Streamwalker.

NOTE to leaders of walks who plan to bring their groups to join one of our walks. While we always welcome more people to our walks, it would be appreciated if you would make arrangements with the walk leader well before hand. Adding a significant number of people (eight or more) at the last minute can make it difficult to see that all get the benefit of the walk You can e-mail The Streamwalker and he will attempt to get you in touch with the walk leader so you can make special arrangements.

No charge is made for Lost River Walks. Toronto Green Community and Toronto Field Naturalists provide these and other walks and events as a public service. If you would like to support the work of these organizations, you may join TFN or TGC. Information on joining is provided by walk leaders or you may check their websites: Toronto Field Naturalists or Toronto Green Community.
