I think this should work:

$builder->add(
    'channels',
    'choice',
    array(
        ...
        'data' => array("monday"),
    )
)

I have realized that it's working I just forgot something in my variables when I tested with an array with multiple elements . CiTNOH is also explaining it

This One worked for me (Symfony 2.3.x):

$days = array("monday" => "Monday","tuesday" => "Tuesday","wednesday" => "wednesday","thursday" => "thursday");
    $builder->add('channels', 'choice', array(
        'choices' => array(
            'days'  => $days,                
        ),
        'multiple' => true,
        'expanded' => true,
        'required' => true,
        'data' => array("wednesday","thursday","tuesday")
    ));

Note: Use the key index to set the Data not the value. "Tuesday" will not work here as "tuesday" does.

Still works in Symfony v3.3 (when used with regular v3.3 syntax). Tnx.

Remove the choices key in the data array:

$builder->add( 'channels', 'choice', array( ... 'data' => array("monday") ) );

Your solution is throwing the following exception : "Notice: Array to string conversion in /xxx/xxx/xxx/vendor/symfony/symfony/src/Symfony/Component/Form/Extension/Core/ChoiceList/ChoiceList.php line 457"
