EPSG:22657 NAD83(CSRS)v6 / MTM zone 17
Projected system (Transverse Mercator) in use: Canada - Ontario - west of 94.5°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.
