Very good question! I'm honestly not the most up to date with ADS-B and diversity nuances (and Garmin's answer to these) besides some basic knowledge (Canada's rollout plan and the fact that diversity is required for aircraft operating in Canadian and US airspace both)However, I feel that you deserve a more fleshed out answer than I can provide this morning (and you've piqued my interest also), so I'm going to learn and get some info together for us and come back tonight with a great answer. Stay tuned!
