8. During the ceremony, the officiant shall address the intended spouses using the text in Schedule III or Schedule IV, as the case may be. If the officiant solemnizes more than one marriage or civil union at the same time, the appropriate text shall be read only once.
The text shall be read in French or in English, as determined by the intended spouses. If either spouse does not understand French or English, the officiant shall ask that the intended spouses provide the services of an interpreter at their expense.
