Thirsty City Self Guided Tours

Sunday, October 21, 2018 2:00 pm - Pass the Glass Water Walk on Garrison Creek
Come Walk with the Rivers Rising Ambassadors!
Explore Lost Garrison Creek, a lost lakeshore, the Bentway, and new futures for the mouth of the Garrison. Bring your water bottle, and wear blue as we embody the watercycle and carry water along the course of Garrison Creek to the lake. Stops along the way include the blood sewer, the smelter, the Bentway, the mouth of the creek, most polluted quay at the lake, and the fish habitat restoration project at Spadina Quay. We've left extra time for the exploration of the Bentway with Ilana Altman as there is so much to see there. This walk continues our series of walks around the Core Circle, a blue-green liminal zone around the city's downtown Core as defined by Toronto City Planning.

Walk leaders: Darlene King, Reno King, Helen Mills, Leah Lem and Ilana Altman.

Meet at the northwest corner of Walnut Avenue and Wellington Street West. Walk is approx 2.4 km and ends at Spadina Quay. Mostly on city streets with a few stairs and uneven surfaces.

Sunday, November 18, 2018, 2:00 pm - Wonscotonach walk
The Lower Don River is always changing: As the Queen St. bridge translates Heraclitus, “The river I step in is not the river I stand in.” We will explore the changes, hydrological, biotic, mechanical and artistic, shaping this well-traveled part of downtown’s liminal Core Circle and examine opportunities to expand Wonscotonach Parklands, a name for the Don that settlers assumed from the Mississaugas. This linear 2.5 km walk includes some uneven ground.

John Wilson leads with friends.

Meet at the corner of Mill St. and Bayview Avenue, a short distance east of the Distillery District streetcar loop.

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.
