A/HRC/45/12/Add.3 contained high level mercury contamination. Monitoring consisted of blood and/or hair analysis on request. Para 37, last sentence, comments: Water and soil are not a major source of exposure – consumption of piscivorous fish with methylmercury is. Para 38, 2nd sentence, comments: The quoted report actually says on page 105: “Over 58% of the Grassy Narrows and Wabaseemoong community members examined by Japanese doctors specializing in mercury poisoning have been diagnosed with or are suspected of having Minamata disease, a serious neurological syndrome caused by mercury poisoning.” The only authority that can determine legitimately and in accordance with Canadian medical professional standards the presence of neurological disease attributable to mercury poisoning in Grassy Narrows and Wabaseemoong is the Mercury Disability Board, which operates in collaboration with communities and employs licensed family physician and a neurologist to conduct assessments. Para 39, 2nd and 3rd sentence, comments: This statement does not reflect the work that is being supported in this area, such as the Joint Canada- Alberta Oil Sands monitoring: https://www.canada.ca/en/environment-climatechange/services/oil-sands-monitoring.html Para 47, 3rd sentence, comments: This sentence is not accurate—the census had reported on the median income in communities. i.e. “A Canadian Press review of census figures for areas identified as Indigenous communities found about 81 per cent of reserves had median incomes below the low-income measure, which Statistics Canada considers to be $22,133 for one person.” https://nationalpost.com/pmn/news-pmn/canada-news-pmn/early-census-figures-showdepth-of-low-incomes-in-indigenous-communities. Para 47, 5th sentence, comments: The generalized statement that toxic heavy metal exposures are generally higher in Indigenous peoples than in the general Canadian population is not accurate. There is a need to be precise with respect to the findings as results differ by geographic location and specific heavy metals. Reference(s) should also be provided. Reports can be found at www.fnfnes.ca. Para 47, last sentence, comments: This sentence should be referenced. Para 56, 2nd sentence, comments: The word “programmes” should be removed. Para 81, first sentence, comments: There is a need to clarify which project this sentence is in reference to and provide examples. Comments from Natural Resources Canada General comments: References to “Trans Mountain Pipeline” should be corrected to “Trans Mountain Pipeline Expansion”. 13
