EPSG:22355 NAD83(CSRS)v3 / MTM zone 15
Projected system (Transverse Mercator) in use: Canada - Ontario - 91.5°W to 88.5°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.
