I don't think the example you cited is applicable to Hattoba's case because in the example your cited, this applicant only lived in France for one year (365 days) and then became a permanent resident. 3 years after this applicant became PR, he/she applied for citizenship. Therefore, within a total of 4 years specified period of time in the instruction, this applicant provided a police certificate which covers the 1 year when he/she lived in France. This is also based upon the assumption that this applicant obtained the police certificate just one year before he/she became PR.
In Hattoba's case, she (I assume, sorry and correct me if I am wrong) lived in Turkey for 1.5 years before becoming PR in July, 2015. I assumed that Hottoba obtained the police certificate from Turkey 1.5 years before she became the PR. 3 years later, on July 25, 2018, she applied to citizenship. Therefore, between the time Hattoba obtained her police certificate from Turkey for the immigration and the time she applied for citizenship, it is 1.5+3=4.5 years. It is beyond the 4 years period of time specified in the instruction. The only reason that I can think of that Hattoba didn't get the request to submit a police certificate from Turkey when she applied for citizenship is that Hattoba's police certificate from Turkey when she applied for immigration is within the range of 4 years which means although she lived in Turkey for 1.5 years before becoming a Canadian PR, she submitted her immigration application with the police certificate from Turkey within the last one year (365 days) and obtained her PR status within that year.
This is my second thought on Hattoba's case. Anyway, I think it is still safer to have one rather than waiting to be requested to submit one which for sure causes more delay.
