Can you think of any other turbocharged twin?
I feel that my knowledge of airplanes is being tested... okay... Turbo Aztec, Turbo Navajo, Turbo Seminole, Cessna 303, 320, 337, 340, and many 400's, Beech turbo Baron, so there are choices in this category I have not flown the Seminole, 320, 400's or Baron, so cannot speak about them first hand.
I, sadly, find Canada to be a Third World country in aviation compared to the US
I guess that we see this differently, I've flown in 47 states, and 21 other countries, and found aviation in Canada to be an ideal balance of low on restrictions, very easy airspace, and adequate in infrastructure in each of the ten provinces, and three territories I have flown in. I have found the cost to fly in Canada to be comparatively low, considering some landing fees I have paid in Europe and Scandinavia. As for places to fly to, I cannot imagine more opportunity than one would find in Canada. Beaches of PEI to the mountains in BC, the fjords of Labrador to the thousands of welcoming lakes in Ontario, and I could always buy gas where i needed it. My personal record is flying to camp on the shore of a beautiful lake and waterfall, 93 miles away from the nearest other person or settlement of any kind. Ahhhh.....
both the government approach, infrastructures
Which is what is paid for by taxes and user fees which one might choose to pay. The US has ten times the population for less area, so yes, they have more financial basis for infrastructure.
It's actually much shorter for me to fly to the US and than anywhere in Canada, if I need to
Sure, I think that is the case for 90% of Canadians. I do have Canadian friends, who own N airplanes, keep them in the US, and drive to the airport in the US to fly them. As you express great satisfaction with US aviation, that's probably your best option, just know the rules about the occasional trip in which you might bring the plane to Canada.
