I'm trying to georeference a map from the Canadian National Topographic System. The paper map says it's zone 18T, but when I go to edit the spatial reference, that's not an option, only 18N. How do I find the correct projection? I know I can create a new projection, but I can't find the specific information for 18T to enter. Any help would be much appreciated!

18T is the 100,000m grid square...in GIS world, everything is designated as North (N) or South (S) of the equator, so add to the confusion grid square 18N is in UTM lune 18N and 18T is in lune 18N, so skip the map designation of the grid square and focus on the zone (ie 18) and whether it is N or S of the equator.
