canadian theatre

[whitetrail at HALHINET.ON.CA]

Hi there,
 
I am doing some research on touring Canadian theatre companies and vaudville
shows from the turn of the century to the mid 1920's. Would you have any
advice on whom I should speak to and on what books I might be able to find
on this subject?  I have The Oxford Canadian Theatre book and find it very
useful.
 
Thank you very much for your assistance.
 
Marci
