EPSG:2033 NAD27(CGQ77) / UTM zone 19N
Projected system (Transverse Mercator) in use: Canada - Quebec - 72°W to 66°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.
