EPSG:2294 ATS77 / MTM Nova Scotia zone 4
Projected system (Transverse Mercator) in use: Canada - Nova Scotia - east of 63°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.
