it has to do with the # of wires on the pole. i.e. this pole is 3-phase (3 wires) therefore there are 3 transformers. there are some single-phase areas left, but that's in low density SFH and you'll only see 1 transformer there. that's generally why most poles have bundles of 3. its rare to see a # of wires not divisible by 3. they don't really build single-phase anymore since it has limits on how much power can be delivered, plus 3-phase is more stable and i highly doubt there is any single-phase downtown.
generally you'll only see transformers where the power is being taken and going somewhere; i.e. to a property/customer/etc. that pole for example goes underground hence it has the transformers since underground transformers are huge and expensive.
from what i can tell in the photos, there's been a lot of changes going on with regard to the development. my guess is they'll underground everything adjacent to the property. its actually a lot more complicated to deal with hydro poles than people would realize. they take a lot of work/planning to move around. i would be curious to see the schematic of the area to see where everything goes.
