New research released by Gravel Watch Ontario, Simcoe County Greenbelt Coalition and Environmental Defence suggest that massive amounts of aggregates for the Bradford Bypass and 413 highways will come from pits in the 905 and the Greenbelt.
Mining these aggregates will have serious impacts on nearby communities and must be addressed in environmental reviews of the proposed highways.
According to the research, building the two highways will require approximately 3 million tonnes of new aggregate, and will increase truck traffic within affected communities by over 130,000 truckloads during construction.
The analysis shows that several communities within the 905 region are more at risk of becoming the future source of the highways’ aggregate because of their proximity to the proposed routes of the highways, the amount of potential aggregate resources available, and concentration of existing permits within particular areas.
This choropleth map is segmented by municipality, and weighted according to a scoring system that combines four scores:
PER_SCORE
For the PER_SCORE the sand and gravel mapping, which were separate files, were combined, the built up areas in the municipality were then subtracted from the combined file, and the result was then measured as a percent of the total area of the municipality. Scores are from 1 to 4, representing 25% increments.
DIST_SCORE
The distance scores are derived from the 20 kilometre and the 50 kilometre distances from the proposed projects. The 50 kilometer radius from the projects is based on a conservative estimate, provided by Gravel Watch Ontario, of the distance from which aggregate resources are normally sourced for projects, with that distance sometimes being expanded outward to 70 kilometers. A score of 2 was given if the municipality was within the 20 kms radius, and 1 if it was within the 50 kms radius. For municipalities within the 20 km radii of both projects a total of 4 was given, and likewise, if a municipality was within the 20 km radius of one project and the 5 km radius of another, it got a score of 3.
TON_SCORE
The tonnage score is based on a decile, with municipalities receiving a score of between 1 and 10, where 10 represents the highest total tonnage permitted within the municipality.
DEP_SCORE
A depth score of aggregate resources based on mapping by the Ontario Geological Survey (OGS) was included to give an additional metric of impact. Depth data are provided by OGS in four categories: Less than 1.5m; 1.5m to 3m; 3m to 6m; and Greater than 6m. DEP_SCORES were apportioned from 1 to 4, with 1 for 1.5m and 4 for Great than 6m.

Bryan Smith, of Gravel Watch Ontario, has been long involved with local aggregate issues and knows what kind of burden this will place on the rural communities that could be affected.
“These highway proposals are being touted as a net benefit, but the communities where the pits and quarries would make a Swiss cheese of the landscape will not feel the same. From increased truck traffic, wear and tear on local roads, reduced air quality, to issues with groundwater, aggregate comes at a high cost to the host municipality and its residents. There is no net benefit. Consequently, many municipalities are asking the province to make aggregate pay their fair share.”
The rock, sand and gravel extraction and its impact on communities up to 50 kilometers from the proposed routes is just another example of how the province is pushing forward these highway proposals without a full examination of their costs and impacts.
The “Aggregate Site Heatmap” is meant to show clustering of aggregate sites. This map uses one source of information shown two different ways – a heatmap, which draws attention to the density of sites, and the sites themselves, shown as polygons.
The heatmap uses data from the “Aggregate site authorized – active” file provided by the provincial government, with the sites, which are provided in polygon form, converted into centroid points. The size of the polygons is calculated into “AREA” and the centroid points are weighted by this metric.
The Greenbelt boundary is included to indicate impacts that aggregate mining may have on an area many Ontarians believe is protected from development, as well as industrial, activity. While development, understood in a strict sense of housing, may be restricted, the knock on effects of road and highway construction, this data shows, are largely not.
A measure of aggregate impact on the Greenbelt was arrived at by calculating the surface area of aggregate mines located within the Greenbelt AND within the study area. The result shows that 29% or the study area is covered by Greenbelt and 39% of the surface area of aggregate pits located within the study area are to be found within the Greenbelt boundaries.

Tim Gray, Executive Director of Environmental Defence, is concerned that environmental assessments of the highways won’t be considering the impacts from required aggregate.
“The shocking scale of the aggregate needed to build these highways means impacts will be felt by communities across a number of regions. The federal and provincial governments have an obligation to assess and address these widespread impacts as part of a robust and thorough environmental assessment of the highway projects.”
The mapping also shows that nearly 40 per cent of the aggregate sites likely to supply material for these projects are located within the Greenbelt.
Expansion of those pits puts at risk the crucial ecosystem services the Greenbelt provides, such as clean water, fresh air, healthy food, and habitat for wildlife. These impacts of aggregate extraction on the Greenbelt are compounded by the fact that they are being used, in this case, for projects that run through the Greenbelt, and which will likely lead to increased development pressure on it.
Margaret Prophet, Executive Director of the Simcoe County Greenbelt Coalition, believes that the highway proposals are yet another example of how this government has targeted the Greenbelt on behalf of developers.
“We heard promises that “we’re not going to touch the Greenbelt,” and yet this government wants to run two large highways right through it. The demand for aggregate, and the fact that much of it is likely to come from within the Greenbelt, only makes matters worse. The narrow focus on localized impacts creates a situation in which the Greenbelt is left vulnerable to a death by a thousand cuts. The impact of aggregate mining for these highways is a perfect example of this.”
The coalition’s research shows there is little that municipalities can do to protect citizens and ensure a healthy environment in the face of pressure from the aggregate industry.
Tim Gray adds, “The province is knowingly putting communities and the Greenbelt at risk from increased aggregate extraction to build destructive and unnecessary highways. And thanks to recently passed legislation, they have removed almost every tool municipalities used to have to limit or control these impacts. The communities located in these extraction hotspots need to be aware that if these highways go ahead it will impact them, even if they are far from the highways’ routes.”
There are a lot of misconceptions, myths, and misunderstandings regarding the role that highways and cars play in our economy, and the impact they have on our environment and communities. Many of these are coming to the fore with the Bradford Bypass. Here we address some of them.
The provincial government is proposing a highway that would connect the 404 with the 400. The proposed route passes along the northern edge of Bradford, and through portions of the Holland Marsh.
Governments have failed to act to protect our communities and the futures of our children and grandchildren, and they continue to treat our environment as if it’s incidental to life, rather than a foundation for it.
We need strong community organizations to fight for our future, now more than ever.
