  • Like many cities in Southern Ontario, St Catharines had a Vernon city directory, which means that there is no classified business directory between 1970 and 1990, so there may be missing chains during these years.
  • I am not 100% certain that the listings for Thorold between about 1940 and 1980 are complete. It is unclear how reliable the coverage was for those years.
  • There’s no evidence that any of the Carroll’s stores in St Catharines made the transition to Grand Union and Steinberg/Miracle Food Mart.
