Strapping for 2x4 before drywall?

Do you need strapping on the walls to attach drywall or is it only on ceilings?

You don't really need it on ceilings either. That's a Canada thing.

I thought it was because the joists flex and the strapping helps prevent the drywall from cracking. Yet on walls the flex is not as much?

You can believe what you want, Canada is a free country too.

Most homes have approximately 8 foot ceilings and you can get drywall in 8 foot lengths ( 4 foot wide), therefore all the wall drywall joints can be vertical and land on a stud if the studs are on 16 inch intervals. Dry walling ceilings is more difficult especially if joists are not on 16 inch centers and some walls are parallel to the joists and fall between joists. Usually easier to install strapping. Will have 4 foot joints (anchored every 16 inches) unless a single sheet of drywall is longer than room in direction of strapping. If there are 4 foot joints, stagger them.
