Prince Charles and his wife, Camilla, the Duchess of Cornwall, have begun a three-day visit to Ontario after touching down in Toronto.

On Wednesday afternoon their plane landed at Pearson airport, where they were greeted by Ontario Premier Dalton McGuinty.

The couple was scheduled to meet privately with McGuinty, and to attend a government reception Wednesday night. Camilla was to visit the Royal Conservatory of Music in downtown Toronto.

Charles met with business leaders in downtown Toronto to discuss social responsibility.

While in the province, the duchess will also stop at Hamilton's Dundurn Castle, the home of Sir Allan Napier MacNab, Canada's pre-Confederation prime minister and one of her ancestors.

This is the 15th time Charles has toured Canada, but it is the first time he has visited since his marriage to Camilla in 2005.

During their stay, the Royal couple will visit Vancouver's new Olympic Stadium, open Toronto's Royal Winter Fair and participate in Remembrance Day ceremonies in Ottawa.

On Wednesday morning, the third day of their 11-day tour, Prince Charles lay a wreath at St. John's National War Memorial in Newfoundland.

The ceremony, which took place under clear skies before a small group of onlookers, was to commemorate the province's war dead in the lead up to Remembrance Day ceremonies on Nov. 11.

"He was invited by the Canadian government to be here at this time so he could honour the dead of not only two world wars but also Afghanistan," Ingrid Seward, editor-in-chief of Majesty magazine, told CTV News Channel. "He's flying the flag of the military and he's here to pay homage."

The British Royals arrived in Newfoundland on Monday afternoon, and were greeted by a round of applause by people waiting at the St. John's airport. Both Charles and Camilla were sporting two Remembrance Day poppies on their coats as they greeted local politicians waiting for them on the tarmac.

The couple was quickly whisked away to their first event, an official welcoming ceremony in St. John's, where they were greeted by Prime Minister Stephen Harper, Labrador Premier Danny Williams and Gov. Gen. Michaelle Jean.

On Tuesday, Charles and Camilla stopped in Cupids, N.L., the site of the first English settlement in Canada. Prince Charles described the community as "emblematic of the resilience and determination" with which centuries of immigrants have come to Canada in search of a better life.

They were joined by Harper, his wife Laureen, and Williams for the tour of the site, which is located on the site of a plantation that dates back to 1610.

The Royal couple is scheduled to make several stops in Ontario, British Columbia and Montreal before leaving the country from Ottawa on Nov. 12.
