Even Now – In This Second Decade Of The 21st Century! – Low-Density Urban Sprawl Continues To Threaten What Is Left Of Our Natural Spaces In The Golden Horseshoe

By John Bacher

Tragically few seem to appreciate the wonders of our relatively well ecologically restored landscape around the eastern edge of Lake Ontario where most of the province’s population lives.

In the 1950s, part of what is now the core of Ontario’s Greenbelt, the Oak Ridges Moraine, was a sand blow desert, bereft of trees. The Niagara Escarpment was a naked rock pile. Development even crowded into stream flood plains, resulting in eighty seven deaths when Hurricane Hazel hit six decades ago.

One of those responsible for the green transformation with its significant increase in forest cover even in the heavily urbanized Don watershed was the visionary ecologist, Charles Sauriol. An ignored prophet before Hurricane Hazel, he then rescued river valleys and the Niagara Escarpment with the help of conservation authorities and his Nature Conservancy of Canada.

Part of the ecological recovery of our region can be seen in the return of species that had vanished because of human abuse of the environment. Sauriol in his lifetime was happy to see the return of one-the Belted Kingfisher, which he compared to meeting a long lost friend. Since his death in 1995 we have seen the return of more species such as beaver, mink and white tailed deer.

In virtually all parts of our homeland, significant forests with a growing coverage across the landscape that has been key to ecological recovery across the GTA/Hamilton/ Niagara area, is well protected. All of the eastern Lake Ontario watersheds have strong tree bylaws modelled on those of Halton Region. These impose significant fines on landowners who illegal cut down trees without a permit. Most of the significant forests of more than 10 acres are in the ownership of public agencies, or various conservationist landowners, such as the Bruce Trail Conservancy.

The recovery of what is commonly called “the Golden Horseshoe” is however, imperilled and fragile. Climate change, which threatens to make cities horrific heat islands and dry up summer streams, requires more forest cover.

What is most ominous is that there are serious threats to our existing forests. This is no more obvious than tthe nearly 100 acre (99.7 to be exact), David Dunlap Forest in Richmond Hill. It was gradually reforested from 1938 to 1980 to provide a forested buffer against noise and light pollution for the University of Toronto’s David Dunlap Observatory.

It is proposed to remove 44.2 acres of the existing David Dunlap Forest block for residential development through zoning changes now being reviewed by the Ontario Municipal Board. (OMB) If approved, this would degrade and fragment one of the biggest remaining forest blocks on a major branch of the Don River, German Mills Creek. It would dump more water during precipitation events on the Don River, which in 2013 experienced massive flooding that shut down GO train service. 

Like most of the Greater Toronto Area’s existing forests, that of David Dunlap was consciously created for conservationist reasons. Its donor to the University of Toronto, Jessie Dunlap, was a patron of Men of the Trees. This organization composed largely of World War One Army veterans lobbied successfully for the creation of conservation authorities to reforest southern Ontario. Another donor, astronomer Clarence Chant worked closely with conservation authorities to reforest the site as part of the goals of the Don Watershed plan.

Like other large blocks of restored forests the David Dunlap Forest provides significant wildlife habitat. It supports deer herds and resident coyotes. It is one of the few places in the 

Toronto region where a boreal forest species, which needs large habitat blocks, the Red Breasted Nuthatch, has breeding habitat. It is a wintering area for the spectacular Barred Owl. 

The provincial government can now rescue the David Dunlap Forest at the stroke of a pen through an instrument of the Planning Act known as a Ministerial Zoning Order.

This should be done promptly rather than taking a sanctimonious Pontius Pilate washing of hands attitude that it is before the OMB. Eventually the forest should be publicly purchased as a form of green infrastructure. This will help avoid higher costs such as paying for flooded out bridges, roads and sewers in the future.

  1. During a study of existing development charges it was found that to build a single family home in Halton Region the Charge is $32,000 and in London the Charge is $22,000 yet it was also revealed a few years ago that the development charge for the same single family home in the Niagara Region was set at about $10,000 but the developer only paid a little over 50% of that charge with the taxpayers held ransom to pay the balance. A few years ago when the Regional Government of Niagara decided to add a small increase to the charge they were met with tremendous opposition from developers. In fact it was revealed that one mayor who sat on the Region and whose father-in-law is a developer actually put forth a motion to delay the implementation of the increase…Conflict of Interest?? You be the judge BUT IT IT STILL SEEMS THAT THE DEVELOPERS IN THE NIAGARA REGION ACTUALLY OWN THE REGIONAL COUNCIL.


  2. Thanks John, well said. The developer (Metrus/Corsica), in concert with our Town Council and a sadly misguided grassroots organization called the “David Dunlap Observatory Defenders”, are proposing a lane, 14 streets, and 531 homes for the eastern half of the 72-hectare David Dunlap Observatory Trapezoid. This is madness. – For some background on the scientific case for safeguarding the observatory, cf my long DDO conservation essay linked to the homepage of http://www.metascientia.com/. For some background on the municipal politics, including a fresh threat, in the last few days, of legal action from Metrus/Corsica supporter Councillor Karen Cilevitz, cf http://www.karen-vs-toomas-blog.ca/.

    John: When our plans for the protest walk of 2014-12-27 are fully mature, perhaps you or others could post again to this site, with directions for the public?:


  3. Again, I agree with Joseph Somers. Have any of you actually paid attention to the reports on who wants to be on what committee of Regional Council , and in fact who got on? Welcome to Party Politics/Partisanship of the highest level at the RMof Niagara! Open for Business. But only if you are a Conservative with high links to local, sometimes dubious, ‘business’ partners.

    Anyone asked about the recently hollowed out Port Place in Port Dal recently? Thought not.

    May 1, 2015. As I drove south on Bayview Avenue and came upon the destruction/clear-cut of the David Dunlap forest I was shocked and appalled that once again the developers rule the day. What a damn shame.
    How can I help stop this from happening again? Why can’t a tree be left standing as part of the planning of a residential neighborhood?
    On King Side Road at Bathurst another large swath of existing residential properties has been bought up, re-zoned to allow multiple dwellings and, what trees were there, completely clear cut. Next up will be the next block along King Side Road, north side, moving closer to young street. More large properties, re-zoning signs in place, more trees to come down. This is Oak Ridges and arguably a lone island residential neighbourhood with large lots and many mature trees. Seeing the clear cutting action is shocking and deeply troubling.
    What does our town council do about this? Do they care? Do they just allow this to happen due to the tax revenue from each planned home? where will it stop?
