I think you're being too generous. Not that there isn't a fair argument to be made in that regards about Bathurst, just that he wasn't making it. It's the rest of his post I take issue with, as his comment about retail came across as tacked-on to his broader point where he, in essence, is advocating for the entire raising of the street, which, residential or not, is actually quite urban, a concept which he mistakenly equates with height.
And while Bathurst may by no means be a retail mecca, from pretty much South of Alexandra Park/Dundas to Niagara, there is actually quite a bit of diverse and high quality retail scattered throughout, from 416 Snack Bar on the Northern end there, to Gotstyle at the Southern end, and if you factor in venues such as the Factory Theatre, it becomes that much more interesting of a street.
