That is your MO, accuse people of not having read the article. I have, others have -- the author does not provide proof that any such destruction has taken place.
In her article, Anne Kingston uses, by way of example, Dr. Raymond Hoff, as proof of PM Harper's policy of records destruction. She quotes Dr. Hoff as stating, "Nothing comes up when I type my name into the search engine on [Environment Canada’s] website.” Environment Canada's search engine does not specifically list authors of its reports because the reports are produced by The Crown. If Dr. Hoff provided titles of his reports, one could then refute or support Ms. Kingston's Maclean's investigative assertions.
By way of my own example to see what destruction of records had taken place under PM Harper's mandate (and, because unlike your questioning my integrity of having actually read the article, I did read it; in fact, I read it several times), I searched Environment Canada's website publication search page for a term of interest: "polychlorinated biphenyls report" also known as PCBs.
https://www.ec.gc.ca/rs-mn/default.asp?lang=En&n=0525D4AD-1
So, from a quick perusing of the 215 reports and documents listed, I picked one:
Determination of Level of Quantification for Measuring PCBs in stack Emission and Ash Samples (2001). Hmm, first of all, it should have, by Ms. Kingston's reckoning, been expunged in Harper's 'Fahrenheit 451-like' records burning. A 2001 report still available to the public?
Anyway, I read the selected report and referred to the Environment Canada author's name, "Chung Chiu," then re-searched the EnviroCan publication search site for Chung Chiu under the 'Author' field, and no links came up. I attribute that to my earlier point about Government documents being authored by "The Crown" or "Her Majesty, in Right of Canada." What would Chung Chiu say? That his name has been expunged from EvironCan's records? Or any of the reports he authored? Clearly that is not the case. If I spent enough time reading through each of the 215 results for "polychlorinated biphenyls report" I may even come upon Dr. Hoff's name.
Not satisfied with you/Ms. Kingston/other conspiratorialists accusations, I wondered to myself if EviroCan would at least refer to externally published and refereed publications, providing credit to its scientist in the process, particularly in regard to Dr. Hoff's work at EnviroCanada?
Ah-ha! After an EnviroCan site search for "peer reviewed publications" I get to this page:
Home>Air>Air Science and Research>Monitoring Networks and Data>Monitoring Networks>IADN>Research Publications and I
scroll down to find
35 (of approximately 100) matches for Dr. R. Hoff in a multitude of EnviroCan-linked peer-reivewed publications.
Pure drivel. Dr. Hoff is indeed is referred to by Environment Canada's website, where contributor-specific involvement is provided. I noted in my investigative research that records still exist of hundreds of EnviroCan reports, and that its indexing system is such that credit of such reports is retained by The Crown, to wit Mr. Chung Chiu's particular case.
Furthermore, if I had the time, I would even consider doing an ATI request to Environment Canada for all reports written by, or contributed to by, Dr. Raymond Hoff, while he was a scientist on staff at AES (Atmospheric Environmental Services) or any other Government of Canada element of what is now Environment Canada. Did Ms. Kingston conduct any such ATI requests in her research? If she did and received declination or refusal, that would serve to reinforce her story. If not, then I would question the depth to which she researched the issue, other than in taking purported facts of convenience, without the rigour that one should reasonably expect to be taken by a truly investigative reporter...
I await your rebuttal asking me once again if I actually read the article. :
QED.
