Anthea,
Hello and welcome to MLU.
As with Karmen I originally came onto the Forums seeking information for a friend of mine, liked what I saw and keep coming back.
In finding info on Thomas, I am sure that someone will do their best to help you out, but as a start may I ask for more details on Thomas if you have any ideas.
Do you have any idea who he served with (unit, Corps, Regiment, etc)?
Do you have any idea where he may may have served?
A couple of places to try, if you have not done so already:-

http://www.collectionscanada.gc.ca/g...909.007-e.html
It may be difficult to obtain records from them if you are not a relative (Othere here will clarify the point)
http://www.legion.ca/
The Canadian Legion may be able to help you in your quest.
http://www.legionmagazine.com/
The Canadian Legion Magazine does provide a lost comrades service, as does the magazine for the Royal British Legion.
I hope this is of some use to you, and I am sure that others more expert than I will try and help.
Paul.
