With regard to the Health Canada decision not to certify citronella-based insect repellents: (a) what studies comparing the toxicity of insect repellents containing DEET with repellents containing citronella does Health Canada have at its disposal, and what are the findings of these studies; (b) during its citronella safety assessment, what groups did Health Canada consult to obtain scientific opinions; (c) did Health Canada receive solicited or unsolicited opinions, studies or documents from groups or scientists about the safety or toxicity of citronella used in insect repellent products and, if so, (i) from what groups or scientists did it receive them, (ii) on what date were these documents received, (iii) what were the findings of these documents; and (d) has Health Canada considered, or does it intend to consider, the possibility of creating a new category of products that would distinguish between chemical-based insect repellents and natural insect repellents, thereby allowing for the development of a separate safety certification process for natural products?
