The fact they require ADS-B out and soon, 406 ELT .............. You would think being primarily inhabited, Canada will require such equipment.
The fact that Canada does not yet require this equipment, in no way prevents an aircraft owner from installing it. A few owners never leave southern Ontario, or other well populated areas, so they perhaps see a lesser cost/benefit to having such equipment.
"Affordable" is a very broad term. Two major factors apply: How much money do you have to spend in total, and how much money can you afford to spend to maintain and operate it. I'm not up to date on the costs to operate light twins, I have been out of them for a while. But I do believe that the cost per mile flown for a twin will be much greater than the cost for mile for a single. Sure, the twin offers much greater redundancy and safety for remote operations, and if your operational need justifies that added cost, certainly, do that! But, if "affordability" is on your mind before you purchase (very wise) don't be optimistic about the cost to operate. Do the math for all of the operating costs. The Continental TSIO-360's are good engines, until they need work, then they are comparatively very expensive. I'm not saying that they are not good engines, just not economical. I use to work on the Continental accessories, and the TSIO-360's seemed to be about the most expensive. I have had to do an approval for the fabrication of replacement primary structure parts, as Piper would not support the plane with factory replacement parts. And sure, Cessna is not perfect in this regard, and Beech are know to be very costly.
In my fifty years of GA aviation in Canada, I have seen a lot of airplane languish, because the owners simply lost interest in keeping paying the bills for them. The planes flew less, so inactivity costs went up, and pilot recency went down. And, I've seen "budget airplanes" within the owner's capacity, which flew lots (I owned a C-150 for 35 years, I never worried about the operating cost at all). And, I've seen a few well funded owners, who simply said: Do what it needs to be well maintained. It's not my business to know which approach you'd like to take, but remember my recommended rule of thumb: How much money do you have to buy and airplane with? Buy a well maintained one which costs half that much, and leave the rest in the bank until you need it. If you've done that, you bought an affordable airplane.
