On-Line Maps Galore

The following on-line links should help your historic mapping search of our local Halton Hills area, the County of Halton or other areas of the province. You will want to look for maps that show ownership and any details identified on the map relative to the property.  You will need to know the original lot and concession number to locate your property.
