EPSG:22762 NAD83(CSRS)v7 / Alberta 3TM ref merid 111 W
Projected system (Transverse Mercator) in use: Canada - Alberta - east of 112.5°W. The full definition below, and conversion in one click.
EPSG publishes no simple transformation to WGS 84 for this datum: conversion works on the ellipsoid alone and can be off by tens of metres.
