This is a list of all known chain grocery addresses in St Catharines and Thorold between 1925 and 2019, compiled from city directories, telephone books, and other sources. It is generated through a live Google Spreadsheet so it reflects the latest information I have.
- 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.
- Food City
- Loblaws/No Frills/Zehrs
- Red & White
- Miracle Food Mart
