An NTS index ".kmz" file is available on the CanMatrix FTP site.
When opened in Google Earth, the file shows the entire NTS grid overlaid on Canada and can zoom down to the individual 1:50000 map sheet level.

Calculators

Online Latitude / Longitude Coordinate converters (DMS <-> DM.M <-> D.D)
http://www.earthpoint.us/Convert.aspx (also calculates UTM convergence angle; to 0.1° only)
http://www.csgnetwork.com/gpscoordconv.html
http://en.wikipedia.org/wiki/Geographic_coordinate_conversion

Online magnetic declination calculators
http://www.ngdc.noaa.gov/geomag-web/#declination
http://geomag.nrcan.gc.ca/calc/mdcal-eng.php

Online calculators to convert UTM to Lat/Long and vice versa
http://www.ngs.noaa.gov/TOOLS/utm.shtml (also calculates UTM convergence angle)
http://www.geod.rncan.gc.ca/tools-outils/tools_info_e.php?apps=gsrug
http://www.uwgb.edu/dutchs/usefuldata/ConvertUTMNoOZ.HTM


Geographic Magnetic Calculator (Windows GUI utility), this will to convert UTM <-> Lat/Long, determine the UTM convergence angle and calculate magnetic declination but doesn’t provide the annual change
http://www.resurgentsoftware.com/geomag.html

GeographicLib (Windows, Unix, Linux) includes GeoConvert and MagneticField command line utilities to convert UTM <-> Lat/Long, determine the UTM convergence angle and calculate magnetic declination
http://geographiclib.sourceforge.net/

The magnetic field models required for the GeographicLib MagneticField utility (install the wmm2010 model at least)
