sorry you have another month to mill over all the "what ifs"! ;)
1. No system is perfect. There are still kinked canulas and infusionset/reservoir/battery/other issues with tubed pumps that go right along with the bad pods. So there is no 'rainbows and unicorns' method, in my opinion, but rather what you prefer to deal with and/or be prepared for. Couple that with the fact that most people (and I say most b/c there are some ppl who report on positive things) who have bad experiences will be the loudest (whether online or in other media forms). So the things you read on the internet are not 100% indicative of what you may experience.
All that being said, I don't personally feel that the pods are a burden. If I did, I would choose a different system. I don't carry a ton of extra supplies when I'm close to home/work, b/c I've stashed extra supplies at those locations. So unless I'm going to travel more than about 1 hour from home, I don't carry anything extra on me. My work bag does have an extra pod in it (but I don't carry insulin), my home frig and work frig have insulin in them, and I of course have a few extra pods and some alc pads and a few needles in a drawer at work. I never need them. But that's because even if my pod started giving me warning notices (for example low reservoir or pod expiration notification), I still have roughly 8 hours until it "dies" permanently so I can make it through the day, get home, and change the pod then. When I travel more than 1 hour from my house I always have a small bag (looks like a toiletry bag I'd carry when traveling) that has 6-7 extra pods, alc pads, and needles in it. I will throw it in my travel bag next to my toiletries and then I'll grab a bottle of insulin out of the frig to take as well. Pumping (pumping in general, not just pods) requires some planning, but I feel like diabetes in general requires some planning, so I don't think it's some new burden that you'll not be able to handle.
2. Sorry I'm in Oklahoma so can't speak to Canadian suppliers.
3. I was a MM pump for 5 or 5 1/2 years. I LOVE pumping over MDI. But I LOVE the tubeless factor over a tubed pump. Yes, other tubed pumpers are right that the tube is a nonissue pretty quickly, so it's not that big of deal--until you are comparing a tubed pumped to a tubeless, and then it IS a significant factor. That being said, if you choose a tubed pump you will likely still enjoy it and not be burdened by the tube.
4. People will always have their preferences. For example one could say that the pods have a finite lifespan (80 hours) so the flexibility of being able to fill a reservoir of a tubed pump with 300 units and then using that for 4-5 days is an advantage over being forced to change every 3 days. Yes it's something to consider if you are paying out of pocket, but from a 'prevention of scar tissue' perspective, most everyone should change every 2-3 days anyway, so this sort of "advantage" is really not much of an advantage at all.
But I'm digressing. My point is that you will find folks who would argue their method one way or the other, but ultimately it's about what your comfort level requirements may be that should decide your choice.
