Checking Canadian copyright laws,
it seems to me that the following section applies:
"[...] the work was created before July 25, 1997 [...] the author dies, the work is published, performed or delivered prior to July 25, 1997, [then] the copyright lasts for the remainder of the calendar year in which the work was first published, performed or delivered and for 50 years after that.
So the poems in the 1941 edition are definitely now in the public domain.

The earliest instance of an edition of this complete collection was published in 1941. For this 1992 edition that I have, the "edits" that were done were basically reevaluations of punctuation and of fragments based on manuscripts and scholarly familiarity with the poet's work.
Would I be correct in thinking that MR would not be comfortable with an upload of a copy of these poems, despite the opinion of owl123 above?
