“Here’s what we know: In peak construction years, up to 50 million tonnes of dirt are excavated in Ontario projects, most from the greater Toronto region, at an annual cost of $1.7 billion, according to the Residential and Civil Construction Alliance of Ontario. Industry experts say that roughly 15 per cent of that soil, as much as 7.5 million tonnes, is contaminated and should go to approved landfill or remediation sites. How much of those 7.5 million tones went to approved sites is unknown.
So where’s all that dirt going? It’s impossible to miss the dump trucks. They thunder across country roads to the north, east and west of Toronto, leaving sleepy towns in their dust. Talk to truck drivers at the Tim Hortons in Schomberg and they all say they’re carrying fill from downtown Toronto construction sites. They all say their dirt is clean, but most don’t know what they are carrying.
