A territorial court judge has ordered a psychiatric assessment for a man who held his family captive in a remote Yukon homestead.

The 45-year-old, who can't be named to protect the identity of the children, plead guilty to incest in October. His three daughters are now 13, 17 and 19 years old.

At divorce hearings last year, the man was described as "a one-man cult" who claimed all his actions, which included taking one of his daughters as a bride, were "guided by God".

Charges against the man include incest, assault, forcible confinement, corrupting the morals of children and pornography.

The charges span a three-year period starting in 2007, when the man moved his wife and children from Whitehorse to a remote camp. The camp was about 150 kilometres away from the nearest community.

The man has been in custody since his arrest 18 months ago.

Prosecutors are asking for a lengthy penitentiary term for the man.
