GMC 2008 Savana Van Owner's Manual page 45

In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached. Be sure to read and follow the instructions for
your child restraint.
If the child restraint does not have a top tether,
one can be obtained, in kit form, for many child
restraints. Ask the child restraint manufacturer
whether or not a kit is available.
