A Canadian dark horse contender, Ouellet is seen as a traditionalist closely aligned with the views of Pope John Paul.

He has spoken out against same-sex marriage, calling it "a big crisis, not only a moral crisis, but an anthropological one. We don't know what it means to be a human being any more."

Ouellet also sparked controversy when he banned the practice of general absolution, which purists call a shortcut.

The practice is a type of mass forgiveness ceremony during which Catholics can receive absolution for their sins without confessing their sins.

In an interview with CTV News before Pope John Paul II's death, Ouellet said the position is out of his reach: "It's beyond my capacities."

Although Ouellet has dismissed talk that he could be pope, some speculate he could be the middle-ground candidate if cardinals are divided on the decision.

Ouellet speaks French, English, Spanish, German and Italian, a language that is considered a requirement for the pontiff who would also serve as the bishop of Rome.

At age 60, he is one of the youngest contenders. But if the cardinals want to avoid a long-reigning pope, his age could work against him.
