I just imported a 5 lb. bottle from Fire Bottle

Is your car log started later than 01/01/09?
SCCA 2013:
9.3.23. FIRE SYSTEM
All cars shall be equipped with an On-Board Fire System except Touring,
Spec Miata, Super Touring and Improved Touring.
A. On-Board Fire System Requirements
Cars registered after 1/1/09 shall comply with the following onboard
fire system requirements:
Systems certified to SFI specification 17.1, or
Those listed by the FIA on Technical List No. 16
The following information must be visible of the unit:
• Certification label
• Capacity
• Type of extinguishing agent
• Weight, or volume, of the extinguishing agent
Note that the SFI Spec 17.1 ONLY specifies the system and testing, NOT the fluid/gas used. It say that it must be EPA legal, that's all.
And about the Canadian regs: the rules Dave listed for Halon extinguishers only apply on Federally controlled property or First Nations property. All other Halon systems are under the control of Provincial regulations only.
