Essentially this pictoral is a coverage map of the Maritime approaches to Canada. The circle around the ship represents an approximation of the area that ship can cover for domain awareness (combination of sensors, movement and onboard assets like helos).
Essentially this is the idealized number of ships that need to be at sea to provide coverage of Canada's maritime domain and their types.
You'll notice the numbers are 4/15 RCD, 2/4 JSS, 4/12 Subs, 2/6 AOPS and 6/12 corvettes needed at sea or available to to the tasks.
The AOPs cover the inside routes of the NWP while the subs and corvettes cover the approaches.
The JSS and RCD are the main expeditionary and oceanic approaches including subs, and backed up by corvettes.
Also shows the airforce coverage for MPA's of various sorts.
This is the sort of thing that informs ship numbers, and is the baseline for explaining to the government what is needed to provide Canadian continental defence.
So I get that the numbers of 4 JSS and a minimum of 12 CDC are probably coming down the line at some point. RCN is already pushing for 4-5 JSS, 4 was the original ask back in the day when the whole project kicked off.
