I have no problem with a dedicated aircraft in special livery for use by the PM, GG or others representing our country on the international stage. I am, however, irritated by the (reported?) efforts of the PM's staff to have that image be a reflection of the current party in power. If the livery of the aircraft (or of any other government advertising campaign) is to be close in design to existing logos, then legal protection should be enabled that precludes the use of such logos (or similar enough as to be confused) by any political party (or other such organizations).
Wavy lines, representations of majestic mountains (and the majority of Canadians don't actually live in/near the Rockies), stylized maple leafs and catchphrases are trendy advertising gimmicks. They should have no place on an aircraft representing the "people of Canada". On the same note, use of "Government of Canada" should also be dumped. Those using the aircraft are not representing the "government", they are representing the people of the "Dominion of Canada". Simple, traditional, identifiable and uniquely Canadian - that's all it needs.
