Céline Dion and her manager husband, René Angélil, will be honoured with the Order of Canada in Quebec City today.

Dion, who was promoted to the order's highest level — companion — in 2008, will be officially invested this afternoon at a ceremony at the Citadel of Quebec.

A citation from the office of the Governor General praises the famed singer as "an extraordinary ambassador for Canada" and lauds both her "unique voice" and stage presence as well as her "compassion, generosity and commitment to a number of social and humanitarian causes."

Meanwhile, Angélil will become a member of the order after being appointed last November.

"With determination and extraordinary flair, he propelled the careers of Québécois singers, whose successes now reach well beyond our borders," reads his citation.

The couple is in Quebec City for Dion's concert Une Seule Fois, featuring largely French material, on the Plains of Abraham on Saturday evening.

It is a one-time-only show for the singer, who is in the midst of her second major Las Vegas residency at Caesars Palace Colosseum and prepping a new album for fall release.
