I was reverting a changeset nearby and I noticed

(there are a number of flooded islands outside of the obvious one).

This is likely to the multi-polygons for the Riviere Des Prairies being
a bit of a mess. I've found:

https://www.openstreetmap.org/relation/1747232 (broken geometry, no islands)

https://www.openstreetmap.org/relation/1747225 (broken geometry)

https://www.openstreetmap.org/relation/1769788 (overlaps the above,
island(s) missing, broken geometry)

https://www.openstreetmap.org/relation/1746332 (geometry ok, contains

There may be more.

I suspect that the likely working combination could be 1746332 and
1747225. But over to the local community.
