Do i enter all family members on the same line for northern trip deduction or on seperate lines

As per CRA (Canada Revenue Agency),

Each person living in the dwelling can claim the basic residency amount as a deduction on their return. However, if more than one person claims the basic residency amount for a particular period and dwelling, no one in that household can claim the additional residency amount for that period and dwelling.
