Sheppard in Edmonton, Park in BC use the same underwriter which is AIM underwriting for RV's. Marsh insurance, which is through COPA is good. I recently switched for the reason that with Marsh, you actually are insuring yourself to fly your aircraft instead of the aircraft for liability, meaning that once you are insured you can fly any aircraft that you own or rent and you are liability covered. You still need whatever hull insurance you require on every plane. Also all of your family members are insured through your liability insurance as well through Copa. I did find that Copa insurance has a little cheaper Hull not in motion premium than Sheppard insurance who quoted me. Hope this helps.
