While Edmonton added 100,000 residents in the past 2 years, that also resulted in an extra 65,000 vehicles on our roads (Mayor Sohi recently shared that stat). That's like 90 cars a day being added to our streets. And with most roads not getting wider - especially in areas taking us to major destinations like downtown, universities, schools, rec centres, WEM and other shopping malls, Commonwealth Stadium etc, we definitely need TODs and expanded transit (as well as other viable options like bike lanes/MUPs) to move us around or else drivers are just going to experience more congestion and our streets less pleasant.
And if we're adding 65,000 vehicles every 2 or even 3 years, there is no way our core will be able to manage that parking demand if everyone drives. Nor do we want a downtown that is built to accommodate so much traffic.
