Air navigation is increasingly moving from traditional navigation using ground-based sensors to performance-based navigation (PBN). This involves transitioning to area navigation by implementing navigation specifications and encompasses both Area Navigation (RNAV) and Required Navigation Performance (RNP).
Transport Canada has published a PBN State Plan to assist the Canadian aviation community in the transition to RNAV and RNP concepts and to help plan future transition and investment strategies. The plan is accessible here, as well as from the link below.

Performance Based Navigation (PBN) is one of the essential tools required to improve global aviation safety and efficiency of future Communications, Navigation, Surveillance/Air Traffic Management (CNS/ATM) systems. NAV CANADA has published a CNS Operations Plan, developed collaboratively with our customers, to identify our priorities and future opportunities. The plan is accessible here, as well as from the link below.

The PBN State Plan and the CNS Operations Plan explain in detail the
different types of PBN instrument approach procedures. Essentially, PBN
approaches are titled according to the lines of minima available on the
chart. Approaches published using the chart title 'RNAV (GNSS)' can offer multiple PBN lines of minima: lateral
navigation (LNAV), Lateral Navigation/Vertical Navigation (LNAV/VNAV), Localizer Performance without vertical guidance (LP) and /or Localizer Performance
with Vertical guidance (LPV). Some PBN approaches require special authorization
prior to use. In these cases, the procedures are published under the
chart title 'RNAV (RNP)'; they are annotated with Authorization Required (AR)
and are referred to as RNP AR approaches. Maps depicting the location of
Canadian PBN procedures are available from the links below.

NAV CANADA has produced a video series addressing common aspects of flight operations when using PBN STARs. The series is available here, as well as from the link below.
