Edward VII Volunteer Long Service medal

[Sunray]

"...information on the soldier..." That probably doesn't exist. Very few such personnel records were kept. And the units have been disbanded for 100 years or so.
The Volunteer Long Service medal was kind of like our current CD. Yours is an Enlisted Man's version, last awarded in 1907 for 20 years of service for men in the Volunteer Force(Basically like our Militia). There was one for Officers and Colonials(that'd be us)
Edward VII's was issued starting in 1901.
Value will depend on where you are and what you can get for it. There's one on a Brit Medals Collector's site they say is worth 85 Pounds. $146.85Cdn.
Haven't lived in TO for eons(more than 30 years), but there is or used to be several Militaria shops down town. Then there are gun/militaria shows like this one. Toronto Military Show
