Dirty Hotels: about our rankings

Our ranking of the hotels this year took into account our overall impression of the cleanliness of the room based on visual inspection, black-light testing, microbiological tests including the ATP meter and contact plates and the hidden camera test.

Ranking was determined under the guidance of Keith Warriner, professor at the University of Guelph and one of Canada’s top microbiologists.

They rank from least improved to most:

  1. Best Western
  2. EconoLodge
  3. Holiday Inn
  4. Sheraton
  5. Fairmont Royal York
  6. Super 8
