If you've walked or biked toward Lions Valley Park this summer, you've probably hit an orange sign somewhere near Dundas and wondered whether the whole corridor is a construction zone. It isn't. What's actually happening is two separate Town of Oakville projects, on two separate stretches of the same creek valley, moving at two very different speeds. One of them is going to hand West Oak Trails a better trail than it had before. The other one is going to stay closed well past Labour Day.
Knowing which is which changes how you plan your evening loop for the rest of the year.
Two Trails, One Name, Easy to Confuse
Sixteen Mile Creek runs through the middle of Oakville, and West Oak Trails sits right against its west bank, which means residents here interact with several trail systems that share a name or a location without being the same project. The Sixteen Mile Creek Heritage Trail is an asphalt path built into the creek's western embankment. The Crosstown Trail is a separate east-west corridor that runs along the natural gas pipeline, connecting Bronte Creek Provincial Park all the way to Ninth Line, passing through Lions Valley Park on its way to the Joshua Creek Trail North. The Westoak Trail, a shorter 3.2-kilometre loop with a trailhead about 600 metres from Lions Valley parking, is a third route entirely, and it hasn't been touched by either project.
That overlap is exactly why a lot of neighbours assume "the trail" is closed when really it's one specific stretch, on one specific route, for one specific reason.
The Closure That Isn't Finishing This Year
The Heritage Trail closure is the one you've probably noticed if your regular walk takes you north toward Dundas Street. The Town closed the section just south of Dundas Road and east of Fourth Line after repeated slope failures on the upper embankment between the trail and Fourth Line. This isn't cosmetic wear. The erosion has been bad enough that rock and shale fragments have migrated onto the pathway, and falling trees have blocked it outright.
The Town brought in WSP as consulting engineers to design a permanent slope stabilization solution, and the current target for reopening is fall 2026. That's not a rounding-error delay. It means anyone hoping this reopens before the leaves turn should plan on being disappointed, and anyone planning a fall hiking route through that stretch should check back closer to the season rather than assuming it clears by Labour Day.
The Wider Path That's Supposed to Open This Summer
The good news is happening on the other side of the neighbourhood, on the Crosstown Trail between Khalsa Gate and Sixteen Mile Creek. This section has been under construction since summer 2025, with the contract awarded to Mastercrete Construction and a completion target of summer 2026, which puts it right around now.
What's coming isn't a patch job. The current path is inconsistent-width base coarse asphalt. The upgrade turns it into a four-metre-wide multi-use trail built to the All Ages and Abilities design standard from Ontario Traffic Manual Book 18, wide enough for cyclists, walkers, and mobility devices to share comfortably instead of squeezing past each other. The plan includes twelve pedestrian crossovers and one pedestrian signal at road crossings, plus rest areas with accessible benches, a bike repair station, and bike racks along the route. Locked P-gates at every entrance keep it closed to motor vehicles.
The Government of Canada and the Town split the cost, with Ottawa contributing $1,180,200 through the Active Transportation Fund and the Town adding $796,800. When the earlier Crosstown segment between Neyagawa Boulevard and Munn's Avenue finished, the Town saw a real jump in usage on that stretch, which is worth keeping in mind if you've gotten used to having this corridor mostly to yourself.
Here's the two projects side by side:
| Sixteen Mile Creek Heritage Trail | Crosstown Trail (Khalsa Gate to Sixteen Mile Creek) | |
|---|---|---|
| What's wrong | Slope erosion, shale debris, fallen trees | Nothing wrong, it's an upgrade |
| Affected stretch | South of Dundas Road, east of Fourth Line | Roughly 4 km between Khalsa Gate and Sixteen Mile Creek |
| Started | Ongoing safety closure | Summer 2025 |
| Target completion | Fall 2026 | Summer 2026 |
| What changes | Slope stabilized, trail reinstated | Widened to 4m, paved, new crossings, benches, bike racks |
The Routes That Were Never Touched
If you've been avoiding the whole west side of the creek because of the signage, you're leaving distance on the table. The Westoak Trail route near Lions Valley Park has been open the entire time, unaffected by either project. So has the McCraney Creek Trail, which follows a waterway down from Dundas Street West to the Indian Ridge Trail at the QEW on its way into Fourteen Mile Creek, and the Fourteen Mile Creek Trail itself, which runs from the QEW to Dundas Street West, west of Third Line. None of these show up on the construction notices because none of them are part of either job.
If your usual loop dead-ends at the Heritage Trail closure, the practical move is to shift west onto Fourteen Mile Creek or loop through Westoak instead of turning around and heading home early.
Why This Isn't Just About the Walk
The trail network here does more than connect green space. It's also how a lot of daily errands get done without pulling the car out. The Pine Glen Indoor Soccer Centre and the Oakville Gymnastics Club sit inside this same loop, along with the Glen Abbey Community Centre, which houses a branch of the Oakville Public Library alongside its fitness programs. Grocery runs and quick errands mostly happen at the plazas along Dundas Street West and Third Line, the kind of stops that don't need a car if the sidewalk or trail connection actually gets you there.
That's part of why the Crosstown upgrade matters beyond recreation. Wider paths and signalized crossings make it more realistic to walk a kid to soccer practice or bike to the library branch instead of driving, which is the whole point of building it to an All Ages and Abilities standard in the first place.
It's also why the neighbourhood's enthusiasm for this kind of infrastructure isn't just talk. When the funding announcement happened in 2023, three Sheridan College animation students showed up to voice their support for better bike infrastructure, pointing to the greater mobility it would give students getting around town. That's not the kind of detail that shows up on a generic parks page. It's the kind of detail you only get by paying attention to what's actually happening here, which is the point of writing this at all.
What To Actually Do With This
Check the Heritage Trail closure off your list until fall. Don't plan a route that depends on that Dundas-to-Fourth-Line stretch reopening before then. Keep an eye out for the Crosstown Trail's Khalsa Gate section wrapping up, since a summer 2026 target means it could open any week now, and a four-metre paved path with real bike parking is worth adjusting your route to use. And if orange signage has been steering you away from the whole west side of the creek, remember that Westoak, McCraney Creek, and Fourteen Mile Creek have been open the entire time.
None of this is a reason to think about buying or selling anything. It's just what's true about the ground under your feet this month, and it's worth knowing before your next walk.
