Sure.
Under section 2 of the act, which identifies the duties of the government, the committee adopted amendments to say under paragraph (2)(1)(a.2) that there's a duty to
protect the right of every individual in Canada to a healthy environment as provided under this Act, subject to any reasonable limits;
It then adopted an amendment right under that one, still in the “duties” section, that says in relation to that paragraph I just read about protecting the right, that the government has a duty to uphold principles such as “principles of environmental justice”, “the principle of non-regression” and “the principle of intergenerational equity”.
Now we come to section 44, which is about “research, studies” and “monitoring activities” to support the government in protecting that right. We know now that the right includes those principles, so adding “research, studies” and “monitoring” to protect the right and apply the principles sort of disconnects the principles from the right. You could say that it's already included in saying that it's “protecting the right”.
I hope that helps.
