Canadian Geographic of June 2007 [article no longer online] features the photography of Peter Sibbald – his “Sprawl 905” project (click on “Recent” then on “Land Use”).
He was interviewed by Shelagh Rogers on Sounds Like Canada on June 4, 2007. The interview is available at the link above, as is a CanGeo slide show and a PDF with a number of photos.
His family has lived near Lake Simcoe for generations.
Thanks to Meg Sears for the tip.
