The report found serious problems, including that only one of 45 nurses in the group sampled by auditors finished all five mandatory Health Canada training courses chosen for the audit.
An internal audit raised flagged the problem five years ago.
Vacancies and high turnover rate in these communities mean Health Canada's first priority is having enough nurses to staff health-care stations.
Health Canada also identified 30 "deficiencies" in the nursing stations chosen for the audit. Only four were fixed, but Health Canada couldn't find paperwork to prove it.
In one case, a nursing station residence was unusable for more than two years because of a broken septic system, leading medical specialists to cancel visits.
