Am I doing something wrong if I need code like this in a Controller? Should I be doing something differently?

public ActionResult Details(int id)
{
    var svc = new ServiceClient();
    var model = new MyViewModel();
    model.ObjectA = svc.GetObjectA(id);
    model.ObjectB = svc.GetObjectB(id);
    model.ObjectC = svc.GetObjectC(id);
    return View(model);
}

The reason I ask, is because I've got Linq-To-Sql on the back end and a WCF Service which exposes functionality through a set of DTOs which are NOT the Linq-To-Sql generated classes and thus do not have the parent/child properties; but in the detail view, I would like to see some of the parent/child data.
