Well, they're going from slightly north of 100 CF-18s to 65 F-35s as front line fighters....you do the math.
As the F-35s are brought on line, the CF-18s will be removed from service.
Obviously its not going to be an exact transition and both types will overlap together in the Canadian Forces for a period of time, but that is the basic trend.
And its hardly unique to Canada - in general the size of most Air Forces is shrinking (gradually). In the USAF, if you are a pilot, you can expect to do at least one tour as a UAV "pilot" - which while it is conductive to the home life, doesn't do anything for your logbook.
Don't feel bad for yourself, feel bad for your grandkids. The F-35 (and F-22) may be the last manned fighters the USAF ever has.
