@healer12 i think you are doing it wrong.You have to loop the ion-option.
*ngFor inside ion-option tag
<ion-item>
<ion-label stacked>{{'City' | translate}}</ion-label>
<ion-select [(ngModel)]="dataProvince" name="province">
<ion-option *ngFor="let p of dataProvince" value="{{p.provinceid}}">{{p.name}}</ion-option>
</ion-select>
</ion-item>
