Some are calling for major development but most experts said revitalization steps to date — a walking and biking trail named after Davis in 2015 and the east island’s 7.5-acre Trillium Park — are steps in the right direction.

“Ontario Place was conceived as a family place, with attractions, entertainment, food services, play and theatre areas aimed at the family,” Davis said in a statement, adding its superb Lake Ontario location made it accessible from all directions and “genuinely family friendly.”

“While any site decades old needs renewal and investment, the core idea of a family friendly amusement and enjoyment centre, affordable for all, with perhaps a Ferris wheel, more programming for children, more interactive displays, more cultural and museum facilities, more room for sports and family, makes immense sense,” he said.

Proposals kicked around for years to revitalize the 155-acre park with iconic Cinesphere dome, futuristic over-water “pods” and man-made islands have new urgency as the Ford government says everything, including a casino, is on the table as it seeks a “world-class attraction” for the site.

Opinion | Edward Keenan: ‘Nothing can be saved’ at Ontario Place? That’s simply not true

Comments trigger alarm bells over fate of Ontario Place

Before being toppled last June, the provincial Liberal government solicited but failed to choose from proposals that had to foster culture, innovation and diversity, with no condominiums and no casinos.

Last week PC fundraiser Jim Ginou, reappointed Ontario Place chair by Ford after a stint two decades ago, alarmed some people when he told Queen’s Park Briefing the site is “in complete disrepair … nothing that can be saved” so it can be rebuilt “any way that Ford wants.”

Finance Minister Vic Fedeli, speaking for the government, did not disagree with Ginou, saying: “Let’s look at (everything), let’s not have any closed doors.”

In Davis’s era, the educational amusement park was home to top entertainment and everything from hot dogs to fine dining. “From IMAX films to world class concerts, it was a leader in North American family entertainment, said Davis, honoured in 2015 with the William G. Davis Trail during the first phase of a now-suspended revitalization following the park’s 2012 closure amid sagging attendance.

“What would not make sense is a casino-centered development, priced only for the better off, surrounded by more eyesore commercial or condominium structures.”

Davis, who led Ontario from 1971 to 1985, concluded that Ontario Place should continue putting Ontarians first and “it would be a shame and a disservice if commercial gain replaced the public interest on the present site of Ontario Place.”

Apart from Davis, residents of Toronto and beyond are speaking up, demanding the people’s voice be heard. Organizers of Saturday afternoon’s “Rally Round Ontario Place” have had to move the event to a bigger room, at Metro Hall. All seats were quickly reserved, with a waiting list started.

Some say any Ontario Place plan must include Exhibition Place, the bigger city-owned site to the north with TTC and GO train service near growing the Liberty Village and Fort York neighbourhoods.

As for Ford, he has in the past championed splashy development for Toronto’s waterfront, with possibilities including a casino and giant ferris wheel. Others say housing including affordable apartments, townhomes or condos could inject year-round vitality and capital funding into the mix.

Here is a sample of ideas people have for the site:

• Jennifer Keesmaat, Toronto’s former chief planner, notes there is much planning and data from public consultations to draw on so “we’re not starting from scratch.” The big challenge, she said, is connecting Ontario Place to transit and bustling neighbourhoods on the other side of Lake Shore Blvd. W.

“The Exhibition (Place) lands have been revitalized — there is a stadium there now, a hotel, the (Beanfield conference) centre, so there’s an incredible opportunity to plan the entire area as an event space and a destination that prioritizes access to the water’s edge as a public amenity.”

She envisions a new, direly needed convention centre — a big “signature building” decided by international design competition — at Exhibition Place and connecting that site and the rest of the city to a more natural Ontario Place, with park spaces and use of Lake Ontario.

“Make (Ontario Place) a waterfront park that is all about providing access to the water, activity on the water and is accessible to absolutely everyone in the city and the province,” she said. The entire area becomes “a tourist destination, a regional amenity (and) a space that supports the rapidly densifying areas around it.”

A casino is a “horrendous idea,” Keesmaat added, and condos have no place at Ontario Place. “There is only one water’s edge. We have made this mistake in the past already.”

• Ken Tanenbaum, a developer who specializes in public-private partnerships, led a proposal to the previous government that wasn’t acted upon to redevelop the west island with university and cultural uses, parkland, an entertainment venue and retail. Tanenbaum, whose bid involved the CNE, Maple Leaf Sports & Entertainment, and Live Nation, said he expects to make a different proposal to the Ford government.

Like Keesmaat he thinks Ontario Place and Exhibition Place need to be planned together because of transit connections, and said the walk across the latter can be “lit up” with an interesting weather-shielded path through the Food Building and BMO Field.

Tanenbaum said he believes Eberhard Zeidler’s Cinesphere and pods must remain. “It’s a sacred part of Ontario Place and needs to be brought back to life but there’s very substantial capital involved in the exercise of bringing it back to life,” with modern sewer, water and power, plus shoreline restoration.

That could mean tens of millions, maybe even $100 million, even with a park-like setting, he said, and the Ontario government will “want to see a commercial engine that can create the economics that can allow that to be funded by the private sector.”

• Ken Greenberg, a prominent planner who is speaking at the “Rally Round Ontario Place” event, said he believes in a vision he and others put forward in 2007.

Redeveloping Ontario Place and Exhibition Place could produce a “Lakefront Park” with a grand waterfront gathering place, including recreation, entertainment, major annual events, theatres, marinas, art galleries, restaurants and heritage sites, acting as a major international tourism draw.

“Between buildings and stretching across Lake Shore Blvd., attractive landscapes would be preserved as freely accessible park spaces that would extend like an emerald arm across the waterfront,” while linked parks would draw people from downtown to the east.

• Zahra Ebrahim, a Toronto designer and urbanist, said the province should “play with ideas of how we can mix public art (and) cultural use with green space.

“We have a shot at something like (Chicago’s waterfront) Millennium Park — a great mix of public space, play space for kids, a natural escape and also dynamic and engaging public art.”

• Phil Myrick is chief executive of Projects for Public Spaces, a non-profit planning, design, and educational organization dedicated to helping people create and sustain public spaces that build stronger communities.

“Building a casino or a mall there is a vision for 20 years and it’s a vision that brings benefits to very few people,” he said. “The kind of vision that a downtown waterfront needs should be a 100-year vision, which brings benefits to the whole city on a scale that would dwarf the revenues that a casino will make because of the value that you can bring the city when you envision a wonderful public place on the water. That’s value that doesn’t decline.

“It’s value that stays and builds and increases over time and is shared by multitudes of different actors, including of course, the city, which is looking to improve its revenues through a stronger tax base.”

• Eberhard Zeidler, the 93-year-old chief architect of Ontario Place, said he’d like to see his original concept rejuvenated and enjoyed still as the multi-use space it once was.

“History is history and what happened at one time has meaning still today, just to understand the time and the feeling of the time,” he said. “To just tear it down is to lose something. It’s the same thing as saying Rome wasn’t there.”

The purpose too as an exhibition space and urban park is still meaningful, he said. Neither a ferris wheel nor casino make any sense.

“I don’t know why you have to do something different,” he said. “It doesn’t add anything.”

His daughter, Margie Zeidler, president and creator of the 401 Richmond space in downtown Toronto and an architect, said she agrees there’s no need to start over.

“I agree it’s a disgraceful mess,” she said, noting how parts of the site have been allowed to go unused for years, but she said: “It does not need to come down. It’s not structurally a problem.”

The pods could be better used and reimagined, she said, adding it would be important to preserve the buildings.

• Toronto condo king Brad Lamb: “We need to think bigger.”

“I’d create a boardwalk, a very wide, amazing boardwalk along the waterfront. I’d commercialize it on the interior side … and I’d put bars and restaurants and stores and just a ton of stuff, and I’d make it a massive international tourist destination so that not only local Torontonians enjoyed it, but people travelled for miles to come to it and it was a fantastic experience and event.”

Lamb says the new Ontario Place should have “a yacht club, a proper public yacht club where large, lake-going vessels, 40-to-60-foot boats, can moor up. Why can’t we do that here? Why can’t you pull up to a spot with your boat from Rochester or Buffalo?”

He would make it 60 per cent park public realm and 40 per cent commercialized.

“Let’s make it a generator of revenue for the government, so it’s zero cost to the government, so that it supports itself, or, heaven forbid, what if it made a profit?”

Full statement from Bill Davis

“Ontario Place was conceived as a family place, with attractions, entertainment, food services, play and theatre areas aimed at the family. With its superb location at the foot of the City, bordering Lake Ontario, accessible to highways and public transit from East, West and North, it was meant to be genuinely family friendly. Equally comfortable with Tier 1 entertainment, hot dogs, fine dining, as with folk music, picnicking, ice cream and visiting dignitaries, adjacent to sports facilities and interesting exhibits, it welcomed all. From IMAX films to world class concerts, it was a leader in North American family entertainment.

“While any site decades old needs renewal and investment, the core idea of a family friendly amusement and enjoyment centre, affordable for all, with perhaps a Ferris wheel, more programming for children, more interactive displays, more cultural and museum facilities, more room for sports and family, makes immense sense. What would not make sense is a casino-centered development, priced only for the better off, surrounded by more eyesore commercial or condominium structures.

“Ontario Place is and was a Crown Corporation so as to serve the public of Ontario — those living in the GTA and visiting from away. It would be a shame and a disservice if commercial gain replaced the public interest on the present site of Ontario Place.”
