"The proposed changes would grant the president powers to appoint ministers, senior government officials and half the members of Turkey’s highest judicial body, as well as issue decrees and declare states of emergency. It sets a limit of two five-year terms for presidents and also allows the president to remain at the helm of a political party."

Hmmm... seems to me that the Prime Minister of Canada already has all of these powers.  The Canadian PM appoints the cabinet; the PM controls the appointments of senior Deputy Ministers; and the PM can appoint all of the members of the Supreme Court and of the Superior courts in each province (not just half of them, as in Turkey).  And the PM can declare states of emergencies (e.g., 1970 October Crisis) and sets policies. In Turkey, the leader will be limited to two five-year terms whereas in Canada, a PM can serve longer.  So unless I hear of more specific powers granted by these amendments, I will keep an open mind.
