Calling it a "rare opportunity" that she had never imagined, Alberta's new lieutenant-governor says she's keen to get to work in her new position.

Lois Mitchell was installed as the 18th lieutenant-governor on Friday morning inside the chamber of the Alberta Legislature.

"In my wildest dreams I could not have imagined my life's path leading to this moment," she said.

Mitchell is known for her work as a business leader and community volunteer in Alberta.

Premier Rachel Notley called her a "tireless advocate for women" who "has created opportunity and changed lives from the rink to the board room to the concert hall."

Past premiers Ed Stelmach and Dave Hancock were in the gallery to watch the ceremony. Grand Chief Bernice Martial and Audrey Poitras, the president of the Métis Nation of Alberta, were also there.

Mitchell read from a prepared text and offered spontaneous remarks too. She shared her excitement about the new position and offered a glimpse into what she hopes to achieve.

"I'd like to do what I can for fellow Albertans who need a little help to achieve their goals," she said, specifically mentioning those with intellectual disabilities.

She referenced and paid tribute to former lieutenant-governors, including Norman Kwong — a former CFL football player for the Edmonton Eskimos. She joked that "like him, I promise to cheer for all Alberta teams with equal enthusiasm."

Mitchell takes over from Donald Ethell, who held the position since May 2010.
