Hi Chris,
You are correct. In Canada, the sub-bands by emission type are "gentlemen's
agreements" only, and have no legal or regulatory binding force. We are
fortunate in that we have what amounts to both Region 1 and Region 2 amateur
allocations.
For example, we can work a US SSB station split on 40m; you transmit 7090
LSB and QSX 7185 LSB. We can also work Europeans and JA's etc. simplex on
SSB below 3750, 7100, 14150 etc.

I should have looked at RIC-2. I have a RAC HF Band Plan as of
1995April22. (Note "Plan" not rule.) The Title for each band states a
general bandwidth, 160 6kHz, 80m 6, 40m 6, 30m 1, 20m 6, 17m 6, 15 m 6, 12m
6, & 10m 20khz max bandwidth. 10m is to allow FM and 30m is restricted to
CW, digital and packet.
That is what I interpret, which goes along with what you have said.
An aside, the sub-band plans, as far as I can find out are not strict but
guide lines only in Canada, ie, can operate any mode anywhere (I have heard
LSB below 3.725)
