EPSG:22653 NAD83(CSRS)v6 / MTM zone 13

Projected system (Transverse Mercator) in use: Canada - Ontario - MTM zone 13. 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.
