I couldn't get a ribbon cable last month from what used to be the best electronics shop in town!

You can still get some parts at The Source these days, but not all of them, and not nearly as expansive a selection.
From thousands of operating stores to 500. Had a few in our area all close, so instead of 2-3 miles, now requires 20 miles to get to one. Effectively to some towns/cities it feels like Radioshack is no more because of such a drastic hit to their footprint.
I just remember the RadioShack near my hometown that was full of walls of components. Now you're lucky to find a blank F-connector at The Source in the largest city in the country. Sentimentality got to me.
That said—for other Torontonians, or visitors, there's an awesome (edit: AWESOME) shop on College St between Spadina and Bathurst called Creatron: https://www.creatroninc.com/ (and surprisingly don't discount Long and McQuade [repair shop, Bloor St] for good quality pots and switches, albeit at a markup).
Doing BGA rework with the right tools is pretty trivial. You can teach the average high school kid to do this stuff but it's not worth it when they could just go to college and learn circuit design or programming to create a design for a less educated technician to build. If they'd rather learn the rework, there are plenty of places that will hire them for more than what someone would pay to have their phone potentially destroyed.
That and regulatory capture (think plumbers/ac repair/etc) mean that while the part may cost $25 retail, and it only takes 5 minutes to replace they can get away with charging $400 for it (happened to me recently) because they know its going to cost you more to replace it. Appliance repair is going the same way, as is automobile repair at a lot of dealers/name brand chains. The smaller guys will replace an alternator for $40+parts, but your going to be looking at 250+marked up parts at a lot of places. I had the dealer quote me $800 for a door lock, that I ended up fixing mysel for $2 in ebay parts and an hour in labor last year.
There are very few places remaining where there is enough density of need in immediate parts, live debugging, or cottage industry-style production to sustain markets like the one in Shenzhen. Worse, decline in one part of the market (dev tools for examples) would result in a decline in visitors and business adjacencies that speed the decline of the other parts.
Aside from Shenzhen, I'm only aware of Akibahara (smaller and more consumer focused) and some of the markets in Seoul (one of which is smaller and consumer focused, and the other which is more machining/tooling cottage industry focused).
