I think that we'd need to get a waiver, unless one has already been obtained.

On
https://data.humdata.org/dataset/cod-ab-mar
it says "License Creative Commons Attribution for Intergovernmental Organisations".  That links to the licences page where it says "Creative Commons Attribution for Intergovernmental Organisations (CC BY-IGO)".  That's not a licence that I've heard of before, but it does look similar to a normal "attribution" licence which may be problematic - see https://wiki.openstreetmap.org/wiki/Import/ODbL_Compatibility for other examples.  You have a couple of options:

1) Ask for a waiver from whoever provided the data
2) Ask on the forum c.osm.org to see if anyone has asked for a waiver
3) Ask the LWG whether this licence is actually compatible.
