Another way would be to put them inside an array in conjunction with array_filter to clean out empty strings and implode them:
$vars = array_filter(array($City, $Province, $PostalCode, $Country));
echo implode(',', $vars);
Sidenote: If you want to treat empty spaces also, you could map out trim on elements, then filter:
$test = array_filter(array_map('trim', array('1', ' ', 'test')));
// ^ single space
