By the last week of October, the maples along the Thornhill Meadow Trail have gone the color you see on real estate brochures and nowhere else, and the East Don River is low enough that you can watch salmon working upstream past the footbridge just east of the Church Lane entrance. Dog walkers cut through from Church Lane. A jogger takes the tunnel under the road to reach the tennis courts on the far side. None of this looks managed. It looks like weather did it.
It didn't.
Tucked near one of the park's entrances is a small sign crediting a group called the Pomona Mills Park Conservationists. Most people walk past it the way they walk past a plaque on a park bench. But that sign points to a group whose work has included helping protect a two-acre meadow parcel from development.
The Group Behind The Sign
The Pomona Mills Park Conservationists started in 1999. Two residents, Valerie Burke and the late Dr. Ann Fowle, set out to restore the East Don River corridor running through the park, which sits inside the Thornhill Heritage Conservation District. The group has spent the years since working alongside the City of Markham, the Toronto Region Conservation Authority, and the TD Friends of the Environment Foundation, organizing spring plantings and litter cleanups that have put hundreds of native shrubs, trees, and wildflowers into the ground and pulled hundreds of bags of garbage out of the river corridor.
This is not abstract stewardship. The wildflower meadow on the park's west side draws monarch butterflies every summer. Maintaining the meadow takes ongoing work.
The Two Acres That Almost Became Something Else
In 2001, the Conservationists did something more consequential than pulling weeds. They rallied the community to petition the Town of Markham to protect a two-acre parcel of meadow tableland from development. The petition worked. That parcel is part of the walking loop today, the open stretch where the trail widens and the tree cover breaks for a few hundred feet before closing back in near the soccer fields.
Walk that open stretch this October and it is easy to assume it was always going to stay green. It was not a foregone conclusion. It took a small group of residents deciding, in a single year, that a meadow was worth more to the neighborhood as a meadow than as anything else, and then convincing the municipality to agree with them in writing.
That is the part of the park's story that does not show up on a trail map. The AllTrails listing for the Pomona Mills Park and Thornhill Meadow Trail describes a pleasant 2.1 mile loop, easy grade, good for birding. All true. None of it tells the story of how the meadow parcel came to be protected.
What The Maintenance Actually Looks Like
The Conservationists still run an annual spring cleanup, and the mechanics of it are worth knowing if you have ever wondered who to thank for the state of the trail on a given weekend:
- Rain or shine, held on the soccer field east of Henderson Avenue and Forest Park Crescent
- Cleanup bags provided, gloves are bring-your-own
- High school students can log community service hours
- The event runs zero waste, with refreshments donated by a local Tim Hortons
It is a low-budget, high-effort operation that relies on volunteers to carry it out.
The Festival And The Park Cleanup
For 42 years, Old Thornhill closed out the summer with the Thornhill Village Festival, later renamed the Thornhill Village Cultural Festival, held every third Saturday in September on Old Yonge Street. The Society for the Preservation of Historic Thornhill ran it from 1977 until 2018, when the organizing committee announced it could no longer sustain the event on volunteer labor alone and canceled it for good. If you have seen a Thornhill guide mention the festival as an annual fixture, that guide is out of date. It has not returned.
The contrast is worth noting. The Thornhill Village Festival ran from 1977 to 2018, while the park cleanup has run annually since 1999. The festival and the cleanup are different kinds of community events.
Where The Walk Ends Now
The loop through Pomona Mills has always fed back out onto the village's edges, and it now feeds into somewhere new. La Vecchia, the Italian restaurant that opened at Yonge and Eglinton in 1996 and later added a second location on the lake in Etobicoke, opened its third at 8700 Bathurst Street on November 3, 2025. The Thornhill location has its own touches on the menu: a Polpette exclusive to this address, a Casarecce Zucchine e Gamberi, a Riccioli Bolognese, a pan seared Mahi Mahi with lemon, caper, and fennel. The room seats up to 100 for events and runs themed nights, including a Thursday built around fresh pasta made table side.
For a neighborhood where the big communal gathering point disappeared in 2018, a new restaurant with 100 seats and a standing Thursday tradition is a small but real addition to the list of places where Thornhill residents run into each other. It will not replace what the festival did. It is worth knowing about anyway, especially if your fall walk through the meadow now has a natural place to end.
What This Adds Up To
None of this changes the price of anything or the timeline of a sale. It is simply the layer of local knowledge that separates someone who lives in Thornhill from someone who has only read about it. The trail's story includes the work of two residents who founded the Conservationists in 1999. The group has organized plantings and cleanups in the park. The meadow's story includes a petition that worked in 2001. The festival you might remember, gone since 2018, has not been replaced at that scale, and the spring cleanup continues as a smaller community event. And the corner where your walk used to just end at a parking lot now has a kitchen worth walking to.
We pay attention to details like these because we work in this neighborhood, not because they change anyone's asking price. Shaheen & Company has spent years watching Thornhill's streets and green spaces the way residents do, one season at a time.
