This shouldn't be a surprise, in many different studies or surveys or even from personally living and working in the downtown cores of Calgary, Montreal, Toronto and now Edmonton, a big reason people live downtown is because they want to live and work downtown, certainly not everyone, but many people want to live and work downtown.
Edmonton has had almost nil job growth in its downtown over the last decade plus (and likely even negative job growth) which is reflective of the fact that there has been an abysmal effort to attract employers to downtown. And yes, in a post-covid world where remote jobs exist there are still many employers that are taking up space in downtowns to have their employees work hybrid in the office throughout the week.
We can clean up streets and build parks and have cool festivals which all make living downtown more attractive, but until we put in an effort to attract more jobs to the core, which is the number one reason many people choose to live downtown, we will continue to see the status quo.
