Gardiner and DVP closures: the weekends that change every route

The Gardiner and the DVP, in one paragraph

Toronto's expressway network is two roads — a 1950s elevated highway along the lake that the city has been rebuilding, deck by deck, since the 2010s, and a 1960s parkway up a river valley that floods — and both close more often than any other road a chauffeur drives: the spring maintenance weekends, the charity ride, the marathons, the overnight rehabilitations, the lane reductions that last years, and the Don's high water. The passenger who books a car does not need to know the calendar; the chauffeur does, and this guide sets it out — the roads, the reasons, the calendar, the alternatives, the decision rules, the airport during a closure, the downtown's grid, the flooding, the future, and a worked Ride for Heart Sunday.

The two roads

The Gardiner Expressway — Frederick G. Gardiner's 1955–66 highway, 18 kilometres from the 427 and the QEW at Etobicoke to the DVP at the Don, at grade through Etobicoke and Parkdale and elevated from Dufferin to the Don through the downtown's waterfront, six lanes (three each way), the ramps at Jameson, Dunn, Spadina, York-Bay-Yonge (the rebuilt York ramp), Jarvis, Sherbourne and the Lake Shore's connections, 200,000 vehicles a day, the city's ownership from the province's 1997 download and the province's 2023 upload back (the "new deal" — the province took the Gardiner and the DVP back with their rehabilitation costs), and the rebuild programme's sections: Jarvis-to-DVP (done — the realigned Gardiner East), Dufferin-to-Strachan (the current one, into 2027 and beyond), Strachan-to-Jarvis (the next). The Don Valley Parkway — 1961–66, 15 kilometres from the Gardiner's east end up the Don River's valley to the 401 and the 404, six lanes, the ramps at Richmond-Adelaide-Eastern, Bloor-Bayview, Don Mills, Eglinton, Lawrence, York Mills and Wynford, 100,000-plus vehicles a day, the Bloor-to-Lawrence stretch's Hoggs Hollow-equivalent hills (the winter driving article's Don Mills hill), the Don River beside it and under it, and the flood problem.

Why they close

Rehabilitation: the Gardiner's elevated deck is concrete on steel from the 1960s and the city's programme replaces it in sections — the Jarvis-to-DVP realignment (2019–2023), the Dufferin-to-Strachan rebuild (2024 onward — the lanes reduced from three to two each way in phases, the province's acceleration promising an earlier finish, the daily westbound and eastbound crawls that the rush hour article now counts), and the Strachan-to-Jarvis section to follow; plus the overnight lane closures on both roads for the deck, the joint and the lighting work (11 p.m. to 5 a.m. on weeknights, the red-eye article's hours). Maintenance: the spring closures — each road closed fully for a weekend in April or May for the winter's debris, the street-sweeping, the inspection and the line-painting (the Gardiner one weekend, the DVP another; the city's dates announced in March). Events: the Ride for Heart (the Heart and Stroke Foundation's June Sunday — both the Gardiner and the DVP closed from 2 a.m. to early afternoon for the cyclists; the city's largest single closure), the Toronto Waterfront Marathon (October's third Sunday — the Gardiner's ramps and Lake Shore, the Bayview Extension and the DVP's southern ramps), the Toronto Marathon (May's first Sunday — Yonge, the Bayview Extension and Lake Shore), the Honda Indy (Lake Shore at Exhibition Place for the July weekend — the Gardiner open but its alternative gone), the Caribbean Carnival (Lake Shore's Grand Parade on the August long weekend Saturday), the New Year's Eve fireworks (the Gardiner's Spadina-to-Jarvis closure at midnight) and the Nuit Blanche and Pride closures that reach the ramps. Weather: the DVP's flooding — the Don River rises with a summer thunderstorm or a spring melt and the parkway's low sections between the Bayview and the Bloor ramps go under (July 2013's, July 2024's — the road closed for hours and the cars abandoned), the Ontario 511 and the city's alert the first sign; and the collisions that close a lane or the road for an hour a few times a month.

The closure calendar

The events calendar article has the dated versions each year, and the city's road closures page the official notices.

The alternatives

For the Gardiner: Lake Shore Boulevard (the at-grade road under and beside it from the Humber to the Don — the city's own advice; 50 km/h and the lights, thirty minutes end to end against the Gardiner's fifteen, and closed itself for the Indy and the Carnival), the 401 across the top for the through traffic (the 427 to the DVP via the 401 — 45 kilometres around the city, the 407 above it faster and tolled), the Queensway and Dundas for the west end (the 427 to the downtown via the Queensway, King or Queen — the Etobicoke chauffeur's routes), and the downtown grid (Richmond and Adelaide's one-way pairs, Front and Wellington, King and Queen, Dundas and College — the construction season article's parallel principle). For the DVP: Bayview Avenue and the Bayview Extension (the valley road beside it from Front Street to Pottery Road and Bayview north — the marathon closes it too), Don Mills Road (the parallel arterial from Eastern to the 401 — the Leaside and Don Mills chauffeurs' spine), Leslie Street and Woodbine and Victoria Park for the east, the 404's approach from the north via Don Mills or Leslie, and the Yorkville-to-North York run on Yonge or Mount Pleasant and Bayview. For both (the Ride for Heart Sunday): the 401 and the arterials — the city runs on Lake Shore, Bayview, Don Mills, Yonge and the grid for one morning, and the chauffeur books the Pearson run by the 401 or the Queensway and the downtown run by Lake Shore or the grid.

The chauffeur's decision rules

The closure's type: a full closure (the spring weekend, the Ride for Heart) is planned the week before and the routes set; a lane reduction (the Dufferin-to-Strachan rebuild) is the daily condition and the timing rule applies; an overnight closure is checked at the red-eye departure; a flood or a collision is the 511 and the Waze check at the ramp. The hour: the Gardiner reduced at 8 a.m. westbound is the crawl and the 401 or the Queensway wins; at 11 a.m. the Gardiner is fine; the DVP northbound at 5 p.m. is the rush hour article's parking lot and Bayview or Don Mills wins if the destination is Leaside or Don Mills. The destination: the waterfront hotels (Toronto luxury hotels guide's Westin Harbour Castle, the Delta) are Lake Shore's; the Financial District is the grid's; Pearson has three ways; the Billy Bishop is Lake Shore's Bathurst turn. The check: Ontario 511 at the departure, the city's restrictions feed in the 5 a.m. briefing, Waze at the ramp — the defensive driving article's rule that the chauffeur decides before the ramp and not on it. The ETA: texted at the departure with the closure's effect — "the Gardiner is reduced, taking the Queensway, thirty-five minutes."

The airport during a Gardiner closure

Pearson from the downtown without the Gardiner: the Queensway (Lake Shore west to the Queensway at the Humber, the Queensway to the 427 north — forty minutes from the core), the 401 (the DVP or Bayview north to the 401, the 401 west to the 427 or the 409 — forty-five minutes; the 407 the faster version), or Dundas and Bloor west to the 427 (the surface crawl); the how early to book article's buffer becomes thirty minutes on a Gardiner closure day, the flat rate does not move, and the chauffeur tells the passenger the night before. Billy Bishop is unaffected by the Gardiner (Lake Shore's Bathurst) and affected by the Indy and the Carnival (Lake Shore closed — Front to Bathurst south).

The flooding days

The DVP floods when the Don rises — the summer thunderstorm that drops 100 millimetres in two hours (July 8, 2013's 126 mm; July 16, 2024's), the spring melt with rain — and the low sections between the Bayview and the Bloor ramps go under a metre of water in an hour; the city closes the road, the cars that did not leave are abandoned, and the Bayview Extension floods too; the chauffeur's rule is the weather radar at the departure (Environment Canada's severe thunderstorm warning for the GTA is the DVP's warning), the 401-and-Don Mills route when the warning is in force, and the passenger safety article's dispatcher who pulls the fleet off the valley when the radar goes red; the Port Lands flood protection project (the construction season article) will reduce the lower Don's flooding when the new river mouth is complete and does nothing for the DVP's Bayview-to-Bloor stretch.

The future

The Gardiner East's realignment (done — the tighter curve at the Don and the new Lake Shore intersection), the Dufferin-to-Strachan rebuild's finish (the province's accelerated date — the lanes back to three), the Strachan-to-Jarvis section (the 2030s), the Ontario Line's crossing of the Don beside the DVP and the Gardiner (the construction season article's subway), the Lake Shore Boulevard reconstruction under the Gardiner East, the Port Lands roads' new alignment, the province's upload of both roads and its stated intent to keep the Gardiner elevated (the earlier "remove the Gardiner East" debate settled by the 2015–16 hybrid decision), and the tolling debate that the province ended in 2017 — the chauffeur's next decade of closures is the rebuild's, and the events calendar the annual constants.

A worked Ride for Heart Sunday

A Sunday in early June, both expressways closed from 2 a.m. to 2 p.m., an Etobicoke family of four with a 9:40 flight from Pearson and a Rosedale couple with a noon brunch at a waterfront hotel. Dispatch's Friday note: "Ride for Heart Sunday — Gardiner and DVP closed until 2 p.m.; airport runs by the 427 from the Queensway or the 401; downtown runs by the grid and Lake Shore." 6:30 a.m.: the Etobicoke pickup (the families with luggage article's Escalade) — the Queensway west to the 427 north, ten minutes to Terminal 3 (the Gardiner was never on the route; the closure is invisible to them). 11:00 a.m.: the Rosedale pickup — the chauffeur's text at 10:50: "Gardiner and DVP closed for the Ride; taking Mount Pleasant and Jarvis to Lake Shore; twenty-five minutes"; Mount Pleasant south, Jarvis south past the Gardiner's closed Jarvis ramp with the cyclists visible on the deck above, Lake Shore east from Jarvis to the hotel's Queens Quay door at 11:25 — the S-Class's couple ten minutes early for a brunch they would have reached by the DVP and the Gardiner in twelve minutes on any other Sunday. 2:15 p.m.: the Gardiner reopens; the afternoon's runs are ordinary. Two bookings, two routes set on Friday, no one late, and a closure that only the chauffeur noticed.

Booking around a closure

The engine books the flat rate that does not move with the detour; dispatch sets the Ride for Heart and marathon routes the week before; the chauffeur texts the real ETA. The Gardiner is closed; you will not notice.
