The functions of the governor-general include appointing ministers, judges, and ambassadors; giving Royal Assent to legislation passed by the Grenadian Parliament; and issuing writs for election.

In general, the governor-general observes the conventions of the Westminster system and responsible government, maintaining a political neutrality, and has to always act only on the advice of the prime minister.

The governor-general also has a ceremonial role: hosting events at the official vice-regal residence in the capital, St. George's— and bestowing honours to individuals and groups who are contributing to Grenada and to their communities.

As the sovereign works and resides predominantly outside of Grenadian borders, the governor-general's primary task is to perform the monarch's constitutional duties on his or her behalf.

[2] After an election, the governor-general formally requests the leader of the political party which gains the support of a majority in parliament to form a government.

[8] The governor-general provides non-partisan leadership in the community, acting as patron of many charitable, service, sporting and cultural organisations, and attending functions throughout the country.

[9] The governor-general uses a personal flag, which features a lion passant atop a St. Edward's royal crown with "Grenada" written on a scroll underneath, all on a blue background.
