 There's no mention of simplex in the WWARA proposal, which makes sense since 2m simplex channels aren't congested the way 2m repeater channels are.  However, changing the bandwidth for repeaters does present a bit of an issue for simplex.
-In Canada, [[references/simplex |FM simplex frequencies]] are channelized in 15 kHz spread for 2m and 25 kHz spread for 70 cm.((Also note that above 147.420 MHz, half of the channels are for analogue and half are for digital.))  Again, 70 cm isn't an issue because 12.5 kHz fits nicely in 25 kHz.  2m is again more challenging.  Doing the same analysis as above, one possible plan would add 5 new channels, keep 4 on the same frequencies, and change 21 by at most ±5.0 kHz.
