Vibrancy as a good thing is of course a matter of taste. I think at minimum an area should be vibrant enough to sustain viable well maintained commercial activity. In this sense central Toronto is barely vibrant enough.
This is exactly how I feel. A city can't be all commercial, but its core should contain high or medium level of commercial actitivies in most areas in a nodal fashion, not just on a few streets. When we walk in central downtown, there are too few really vibrant areas, especially when it comes to N-S streets. Yonge and part of Spadina (between Queen and College) and part of Church (near village and south of Queen) are the only busy streets. Bathurst, University, Bay, Jarvis and Sherbourne are embarrassingly residential, when you consider they are in the center of a 6M metro area.
In downtown Toronto, we have a decent amount of retail, along Queen W, King west, Dundas W, Spadina and Yonge, but the city still looks incredibly residential and hardly dense (judging by the number of low rise SFH). There are many many dead quiet streets, small or big with nothing but houses (Tim Hortins and corner convenience stores excepted). Anywhere east of Church st - almost nothing going on; Essentiall all NS streets between University and Spadina - McCaul, Beverly/St George/Huron, and almost all W-E streets as well except those streetcars operate.
On the other hand, vibrancy in most large asian cities exceeds, in my opinion, a threshold after which the level of activity actually decreases the quality of life. I think Tokyo is a particular city of interest to this thread as it is an example of how an inherently ugly (much uglier than Toronto) city can become kind of beautiful as a result of higher standards of care and investment in both the private and public realm.
Agree. the exessive and ubiquitous retail in Asian cities are sometimes annoying, as you can't find peace anywhere. However, it also makes daily life convenient. For example, there are grocery markets everywhere, almost every half a mile there is gotta be one. People don't buy meat and vegetable on a weekly basis. They buy fresh ones every day or every other day. To eat broccoli bought 4 days ago, or meat which have been frozen for a week is unimaginable in Asian cities. This kind of lifestyle is sustained by very high density, which unfortunately sparse Toronto won't be able to support.
In cities like Paris, retail - grocery, small restaurants, bakeries, meat shops and convenient are essentially everywhere. You never have to walk for more than 5 or 6 minutes to get whatever you need, much more like Tokyo or Hong Kong.
Quality of life? I am sure stale vegetable or frozen chicken or beef bought a week ago are not part of it. Parisians buy baguettes every day. How many Torontonians eat fresh baked bread every morning at home as breakfast? This is why I embrace rapidly increasing density because only that can support more sustainable urban lifestyle - if Toronto has half of the density of Paris (currently about 20%), life quality will be significantly improved.
