A piece of historical trivia about North Toronto and the former prevalence of business incorporating the word Hudson, as seen above - Hudson Plumbing Supplies, Hudson Movers, Hudson Shoe Repair, and so on.
Back in the day, telephone exchanges were very much geographically, and they also had mnenomic names. The North Toronto telephone exchanges were all 48x-nnnn, for example 481-nnnn,...486-nnnn, ...488-nnnn. The initial two digits, 4 and 8, were alphabetically denoted as HU, and their mnenomic name was Hudson. So a local North Toronto number would be called: Hudson 1-nnnn, or Hudson 6-nnnn. A number of North Toronto businesses, such as Hudson Plumbing Supplies - seen above - adopted Hudson as part of their name to identify themselves as local community businesses.
This practice was not unique to North Toronto - there are many examples across North America of businesses - especially those dating from the mid-twentieth century decades - incorporating their telephone exchange mnenomic as part of their business names.
