Dominic Calder is the father of Craig and Lucy Calder, and the estranged husband of Maggie Calder. In December 2001, Dominic phoned Maggie to ask if Craig and Lucy could spend Christmas with him. Maggie was reluctant to ask them but Phil Weston pointed out that Dominic is their father and still has a right to see them. Lucy was keen to visit him so he wouldn't be alone at Christmas, but Craig wasn't too keen, preferring to stay with Maggie. Lucy manages to convince Maggie to let them go.
