Ontario is starting to get interesting as to what is and what isn't higher res.
K-W is now the highest res, but Guelph is low res.
A large swath of Eastern Ontario is higher res - most of Kingston to past Gananoque is (past the bridge from the 401 to Interstate 81), Perth is higher res, Smiths Falls is not. Simcoe is high res now, but not London or St. Thomas. The former Hagersville AFB is high res, not Hagersville itself. A large portion of Lambton County is higher res, including Sarnia, but not Kent County (higher res starts just north of Wallaceburg). Owen Sound, Walkerton, Lucknow and Kincardine are higher res, but not Goderich or Hanover.
Parry Sound is high res, but little in Simcoe County.
