In 1911, the Duke was appointed Governor General of Canada. Princess Patricia accompanied her parents to Canada, and she became popular there, on those occasion she wore her mothers wedding gift, the Indian diamond tiara as stomacher, without the center, of a movable ornament like a sarpech on top, with hanging emerald drop.

Sarpech, also known as an aigrette is a turban ornament that was worn by significant Hindu and Muslim princes.

She had her own jewels and tiaras for royal events, because , her mother’s precarious health meant the unmarried Patricia often step in for her mother, as vice-regal hostess, especially during the Duke of Connaught’s tenure as Canada’s governor general from 1911 to 1916.
