Greetings all,

I'm working with map data from Lethbridge, Alberta, Cananda that's in NAD83 
3TM projection. I'm having trouble locating details about the projection 
other than it's a 3 degree projection with -114 as the cental meridian. I'm 
working with qgis and I tried copying one of the other MTM projections and 
changing it to: 

+proj=tmerc +lat_0=0 +lon_0=-114 +k=0.999900 +x_0=304800 +y_0=0 +ellps=GRS80 
+datum=NAD83 +units=m +no_defs

Would this work? Thanks so much.
