From the Guide, it is asking for 5 years of NOA.
- Canada Revenue Agency (CRA) Notice of Assessment for the five (5) years immediately before the application

Since the instructions specify providing just
two items ("
two pieces of evidence"), obviously a NOA (one NOA) from one of the previous five years would constitute one of the two items. That is, any one CRA NOA "
for the five (5) years immediately before the application" is an
example of one of the two pieces of evidence to submit.
For PRs making a routine application, any two items showing presence in Canada should easily be sufficient. That is, for PRs who are living in Canada and have established in-fact residence in Canada, who are not
cutting-it-close in regards to RO compliance and who otherwise do not have admissibility related concerns, for them just about any two items among the described examples (such as any two bank statements or NOAs for two years, or other items which comparably show activity or presence in Canada during the relevant time period), should readily suffice.
PRs
cutting-it-close and who have just recently returned to Canada after a lengthy period outside Canada may want to be more picky in what items they submit, focusing on better evidence (documentation showing active employment at a location in Canada is high on that list), perhaps providing two different kinds of evidence (just one NOA, say, and one other item). But, frankly, the quality of this evidence probably makes very little if any difference in how it goes. Currently the majority (most) PR card applications are approved based on machine screening (whether it is an automated approval or an automated tentative approval subject to a cursory review).
Obviously, PRs with RO compliance related concerns, including PRs not fully settled and living in Canada, among other circumstances in which increased scrutiny could easily be anticipated, have a higher risk of non-routine processing. It is unlikely that the quality of evidence submitted with the application reduces that risk. How this will affect processing times will vary depending on the specific circumstances in the individual case.
If IRCC has RO compliance concerns it will make additional inquiries, which means a longer processing time, and if that does not resolve whatever concerns there are then IRCC may request additional information or documents, and/or refer the application into a queue for investigation (the latter can increase the processing time considerably).
For OP (last year's post), assuming it is for a PR who has not been outside Canada for 1095 or more days during the relevant time period, see response by
@Ponga back then
Unless things have changed, you only need to provide 2 pieces of evidence, so ONE (month) bank statement and ONE NOA will suffice.
Ideally, these should be from different times within the 5 year assessment period.
Note, in regards to supporting documents to be submitted by a PR who has not been outside Canada for 1095 or more days during the relevant time period, there have been no changes in this and none are anticipated for at least the near future.
