This has to do with the qualifications for the appointment of members to the commission. It is recommending:
The commissioners appointed must reflect, to a reasonable extent
—which I think is good to add—
the diversity of Canadian society and must ensure that, collectively, they maintain a range of competencies, including with respect to Indigenous traditional knowledge
We could change that; I would be willing to take out “traditional”:
and worldview, community development and public engagement, renewable and non-renewable energy, and environmental and climate science.
It would help to avoid claims for bias, or not treating some of the intervenors with respect, or the proponent even, if you have a wide diversity.
