What is the official name of the elected members at the provincial level of government?

The name of the elected member's office in a City in Canada is that of Alderman (some also allow Alderpersonor Alderwoman). They are elected to WARDS, which are similar to a district or precinct in the US. The collective name of the body that aldermen belong to is City Council. The head of the Aldermen is the Mayor, who is also the head of City Government (and he/she also has responsibilities for a Ward in some cities.).
