LONDON (AP) — Canadian Prime Minister Justin Trudeau has collected an honorary doctorate and met Queen Elizabeth II during a trip to Scotland.

Trudeau visited the queen Wednesday at her Edinburgh residence, the Palace of Holyroodhouse. Trudeau's office said the meeting was intended to "honor her importance to Canada's history and to thank her for her continued dedication to Canada."

The 91-year-old queen is Canada's head of state.

Trudeau also received an honorary degree from the University of Edinburgh, and praised the strong partnership between Scotland and Canada.

Trudeau, whose maternal grandfather was Scottish, said "15 percent of Canadians have Scottish roots, so Canadians, including me, have a strong link and affinity with Scots."

The Canadian leader is on his way to G-20 summit that is being held Friday and Saturday in Hamburg, Germany.
