Data is in UTM NAD83(original) in most cases, Zone 17N unless otherwise specified. While converting datum and projection settings for vector files is a simple task for most users, the same operation with raster data like orthophoto may require a higher level of expertise. Conversion to other datums such as MTM NAD27 Zone 10, which is typical for City of Toronto data, is a service FBS can provide. A fee for custom labour would apply. Contact us for a quote.
