Hello Andy,
Regarding the licences themselves:
Recent Statistics Canada data appears to be released under a
"Statistics Canada Open Licence" which can be found at
https://www.statcan.gc.ca/en/reference/licence. As far as I know this
has not been approved for importing to OSM. I do not know whether the
editor's activities would be considered an "import" or if the licence
is compatible for non-import use. The OSM wiki at
https://wiki.openstreetmap.org/wiki/Canada#Importing_government_data
does say "Statistics Canada data is used to import street names where
they are missing from the other data sets. It is advised to not copy
the geometry; however, you can use the street names database as a
reference. " - I did not go through the page history to find when and
by whom this was added.
The "Open Government Licence – Winnipeg" is, to my understanding, not
a suitable OSM import data license. This is a long-standing problem
with Canadian open data where licences with the government unit's name
in their name (here "Winnipeg") are considered by OSM a different
licence from the Open Government Licence even if all the words other
than the city name are the same. As far as I know only the Ottawa
community has gone through the (rather slow) process of getting
OGL-Ottawa approved as an OSM import licence. Same question about
whether the edits constitute an "import" applies.
