Nothing of the requirement for 30 hours from a particular country has been made available on the WPC website
If that was the case they would ask for the logbook when applying for RTR P
Your friend must be confusing the 30 hours requirement within last 5 years for renewal of license with the issue of RTR P
That being said WPC can change the rules at any time . As of this writing nothing of that sort has been published . So dont stop obtaining that canadian CPL and RT if you need to
