Older Ontario county road maps

[Andrew T.]

Does anyone happen to know if there there are any online sources for historic Ontario maps that show numbers for county roads?

Other than a 1968 map scan on the Norfolk County website and an occasional picture on the "Vintage Ontario Maps" FB group, I've found nothing.  When I did my own research for "The Highways of Hamilton" last year, 90% of the fieldwork consisted of going to libraries and digging through paper maps.

Not helping is how most Ontario roads are atomized at the municipal level, with every county/region/city doing its own thing as far as mapping and recordkeeping goes!
