Commander Crabbe says he struck out with a brief google, but dogpile led me to lots of info about the probable author of this verse, Lloyd Roberts, the son of nature writer Charles G. D. Roberts, whose stories were a bedtime staple during my boyhood. According to the link, back in 1911 Lloyd Roberts worked for the newspaper in the small B. C. town where I now live. The complete text of his book England Over Seas is available from the Gutenberg Project. If the ghost canoe poem is in that book, I missed it during my quick scan. I'll betcha it's in his book called "Along The Ottawa".

The text of the verse as it appears in my copy of Tales Of An Empty Cabin is:

And always I hear the stir of men dipping
Down to the Chaudiere, their thin blades dripping,
Catch the long low wraith of a bark canoe
And hear the wild sweet chansons of a phantom crew.
