Like the AOPS design, both the RCN and CCG variants all these hulls are PC4 class - Year-round operation in thick first-year ice, which may include old ice inclusions as per Transport Canada - displacement of about 9000 tonnes
PC4 vessels also include Fed Nav's MV Umiak I, MV Nunavik, andMV Arvik Ibulk freighters operating out of Voisey Bay and Deception. They displace about 32,000 tonnes.
...
The Azipod propulsion system, which was proposed for the AOPS, has been employed in the NoCGV Svalbard and in the Double Acting Ships which, like the PC4s, are not expected to require separate ice-breaking services from heavy icebreakers.

Once you get past PC4, into the PC 3,2 & 1 (or equivalent), the number of operating vessels in those classes dwindle exponentially. Canada with 16x PC4, two heavies and up to 6 mediums along with the AOP's (8x PC 5 hull, PC 4 bow), Canada will have likley the 2nd or third largest and most capable fleets in the world.
