The Economist is biased when it comes to some of those rankings such as Top Ranking Cities of 2021 and I take them with a grain of salt most of the time. A lot of those cities are ranked high because of free health care, green policies, and other politically motivated aspects. Tokyo and Singapore IMO are much better than Toronto, safer, cleaner, way better infrastructure and more thriving in terms of night life, entertainment etc. Sydney and Melbourne are also nice cities. Copenhagen never been but heard its really nice. Expensive and most people there are very well off and a smaller population in comparison to other bigger cities so which makes social and healthcare services more accessible. Toronto's infrastructure in comparison to Tokyo or Seoul or other major cities is really far behind. As well, Toronto's population is growing at a high rate, which is driving up real estate and renting prices, alongside we're already seeing a strain on social and health care services across the GTA and Ontario. More money needs to be invested in infrastructure here and health care (Provincial government), because it is lagging.
Yeah like I said, Toronto is relatively safe still for a big city in comparison to other major cities. LA, Chicago, New York, Atlanta, Baltimore, St. Louis, Detroit, Miami, Minneapolis, Cleveland, Washington DC etc. are worse when it comes to overall violence. Still a little worrisome though how Toronto has been heading in the wrong direction since it's pretty easy for a city to be a thriving safe metropolis and then all of sudden have a complete 180. Also, depends on the area in the GTA. Some areas are obviously safer than others, though even still gun violence has reached the suburbs and what are considered safe areas. I remember last summer there was a shooting at Sherway right outside the Joey's. I was there the day before as well. Scary to think something like that would happen in broad daylight out in the west end.
Montreal I find is worse than Toronto. Vancouver I find is better though they have a huge homeless and drug problem. At the end of the day, each big city isn't perfect.
