At 7 p.m., as daylight leaves the lots at 1180 Lakeshore Road West, tunnelling resumes about 45 metres below the edge of Jack Darling Memorial Park. The work happens at the bottom of a shaft beside the park, where a tunnel boring machine is driving east under Lakeshore Road. Peel Region has scheduled the work to run until 7 a.m. every night through roughly summer 2028.
The machine is headed for Elmwood Avenue in Port Credit, about four kilometres east, according to insauga's report on the launch. Peel built this pipe to add water and wastewater capacity for future growth in Port Credit. Lorne Park's busiest park is the starting point, and it will keep its construction site longer than any other stop on the line.
The longest lease on the line
Peel's Lakeshore Trunk Sewer and Zone 1 watermain project, file 19-2215, puts in a 2,400 mm sanitary sewer and a 750 mm watermain along Lakeshore Road between Jack Darling and Elmwood Avenue. The tunnel needs a fenced compound wherever the machine goes in, comes out or reaches an access point. Peel's current schedule for each site:
| Compound | Expected to start | Expected to end |
|---|---|---|
| Jack Darling Memorial Park boulevard | As early as Nov. 10, 2025 | Late 2029 |
| Richards Memorial Park boulevard | December 2025 | Fall 2027 |
| Marina Park, Front Street North | January 2026 | Summer 2028 |
| Wesley Avenue at Lakeshore Road West | As early as Aug. 4, 2026 | Spring 2028 |
| Elmwood Avenue parking lot | May 11, 2026 | Fall 2028 |
Jack Darling's compound was among the first to go up, and Peel's schedule has it coming down last, about a year after the next-longest. It is also where the tunnel begins. In the June 2026 newsletter, Peel said the Jack Darling shaft was "completely dug" and that the tunnel boring machine would begin from there. The shaft at Richards Memorial Park, by comparison, goes down 34 metres.
Another project is also queued for the park. Peel's file 24-2980 covers upgrades to the Jack Darling Sewage Pumping Station, on Region-owned land inside the park. That project is still in early planning and has no construction dates.
What runs while the park is quiet
The tunnelling is planned for nights. Peel says it is quieter than daytime surface construction, and the City granted a noise bylaw exemption so it can run from 7 p.m. to 7 a.m. Speaking to insauga, Peel officials said "intermittent noise may still occur" and that measures would be in place to limit the effect on nearby residents. Overnight tunnelling began July 20, 2026, after a preparation shift on July 13.
That timing is how the park stays usable by day with a 45-metre shaft at its edge. The noisiest part of the job takes place underground, mostly after dark. The parts park users notice in daylight are the fence, the detour and the traffic on Lakeshore.
What the surface looks like through November
The City's Jack Darling Memorial Park page lists the park as open daily from dawn until 11 p.m., with a paved section of the Waterfront Trail, picnic areas, tennis courts, a leash-free zone, a native tallgrass prairie and a toboggan hill in winter. The prairie last had a controlled burn in spring 2025. The City burns it every few years in early spring, when the grasses are dormant. Walking trails in Rattray Marsh Conservation Area are reachable from the park.
Here is how the project shows up at street level on Thursday, Nov. 5:
- The trail detour. Peel has rerouted the multi-use trail on the south side of Lakeshore Road West around the compound at Jack Darling, as well as around the one at Richards Memorial Park to the east. Posted signs mark the route.
- One lane each way to Lorne Park Road. From Oct. 1 to the end of November 2026, Lakeshore Road West is down to one lane in each direction between Jack Darling and Lorne Park Road while the new watermain goes in by open-cut excavation. Street parking is not allowed inside the work area, and access to homes stays open.
- The zones move east. Peel's Sept. 15 update says the lane reductions will generally shift eastward in zones and continue somewhere between Jack Darling and Shawnmarr Road until summer 2028.
- A mural on the fence. The Jack Darling compound wall shows "Mino-nawae-indawaewin / Living in Harmony" by artist Nyle Miigizi Johnston. Peel's project page quotes his statement that the mural shows "how beautifully we are interwoven to this quilt that we call life on this planet."
The mural belongs to the Mississauga Arts Council's Lakeshore Mural Project, which puts work on each compound along the route. Sauga City's mural is at Richards Memorial Park, Soon Cho's on Wesley Avenue, Jinke Wang's on Pine Avenue, Marlon Porter's at Elmwood Avenue, and Keitha Keeshig-Tobias Biizindam's at 5A and 5B Front Street. Following the Waterfront Trail east from Jack Darling takes you past the same tunnel route, compound by compound.
The leash-free zone comes next
For many park users, the most important line in Peel's paperwork concerns the dog area. The Region's project page says the work "will" require additional impacts in the park's leash-free areas, and that Peel will share specific impacts and durations as they are known. The June newsletter makes the same commitment: access to the leash-free areas will change as work zones are set up, and notices will go out ahead of time.
Earlier notices show how Peel has handled this so far. In April 2025, all of Jack Darling's leash-free areas closed from 8 a.m. to 5 p.m. on April 7 and 8 for geotechnical drilling. For the pumping station file, Peel scheduled field investigation for April 27 and 28, 2026, which meant a temporary dog-park closure and the loss of four parking spaces. Both closures lasted two days and were announced in advance.
The City's leash-free rules apply wherever the fence ends up. Leash-free zones are fenced areas where owners supervise their dogs. Outside them, dogs must be on a leash and under control, owners must clean up after them, and anyone walking more than five dogs needs a permit, as set out in the City's leash-free zone guidance.
What Lorne Park gets back
Peel's stated purpose is Port Credit's growth, but some of the long-term benefits land in Lorne Park. Peel's project page lists the opportunity to retire seven sewage pumping stations once the new gravity sewer is in place: Jack Darling 2, Richards Memorial, Ben Machree, Indian Road, Front Street, Elmwood and Hiawatha. Ben Machree and Indian Road are Lorne Park street names. The June newsletter says replacing those stations cuts long-term operating and maintenance costs and gives a system that is "less likely to break or fail during storms."
Until then, the most dependable source of information is Peel's own construction e-notice list. That is where the Region says it will announce the leash-free changes, each move of the lane reductions and any reclosing at Wesley Avenue. For urgent problems, the project line is 905-791-7800, ext. 4409. Peel staffs its social channels weekdays from 8 a.m. to 5 p.m.
Big public works on the waterfront change how a stretch of Lorne Park feels day to day long before they change anything on paper. Knowing which fences come down in 2027, which in 2028 and which stay until late 2029 helps when you're planning around the neighbourhood.
