Last season they won a bronze medal at the European Championships and this season have finished on the podium twice at the ISU Grand Prix and qualified for the final in Japan as one of the top six couples.
John Kerr said: "It's a wonderful feeling to be selected for the team. We learned an enormous amount about competing for Team GB when we were at the Olympic Winter Games in Turin, and of course we're looking forward to repeating that in Vancouver.
"It was a fantastic experience to finish in the top 10, but we're aiming to go even higher in 2010."
McCorkell, from Coleraine, is the seven-time British champion and is believed to be the first athlete from Northern Ireland to compete for Team GB in the Winter Olympics.
"I've been fortunate enough to have won the British title seven times, but the Olympic Winter Games is the pinnacle of our event. I'm thrilled to have been selected for Team GB," she said.
Britain last won an ice skating medal in 1994 when Jayne Torvill and Christopher Dean took bronze in Lillehammer - a decade after winning gold in Sarajevo.

The skating team is the first confirmed British participants for the 2010 Games - which run from 12-28 February, with Team GB expecting to send about 50 athletes across six sports.
Team GB chef de mission Andy Hunt said of the skaters: "I'd emphasise that all of them have had to meet the tough qualifying standards that we established.
"I'm completely confident that the athletes we've selected will do a great job for Team GB and strike to achieve their personal best for Team GB."
