Well, I can tell you there are a few differences for Canada from the FAA norms, namely:
Propeller Aircraft (including turboprop)
MHA to 30000 feet 175 KIAS
Civil Turbojet
MHA to 14000 feet 230 KIAS
above 14000 feet 265 KIAS
Climbing when in holding pattern
Turboprop Aircraft Normal climb speed
jet aircraft 310 KIAS or less
There are some differences for military turbojet aircraft also.
