On March 22, 2008, Transport Canada published a Part I proposal in the Canada Gazette (page 828) that proposes to amend the Canadian safety standards relating to vehicle roof crush and rollover protection (specifically standards 216 and 220). As proposed, the amendments would:
• Increase the applicable vehicle mass from 2,722 kg to 4,536 kg GVWR;
• Increase the force applied from 1.5 to 2.5 times the unloaded vehicle weight;
• Eliminate the maximum force applicable to passenger vehicles;
• Replace the intrusion performance criteria by one that specifies maintaining headroom for an average-sized male occupant;
• Change the title “Roof Intrusion Protection” to “Roof Crush Resistance.”
Comments on the proposal are due June 5, 2008.
