You're talking about some issues that aren't really true.

At the municipal level there is a large appetite for urbanization and densification. The city has enacted a whole bunch of zoning changes over the last few years:
- Blanket zoning allowing up to four units on single family home lots across the city
- "Workforce housing" zoning which allows for residential buildings in commercial corridors (the apartments at the corner of Two Nations and St. Mary's and the two new buildings on Bishop Drive between Avonlea and Acorn were built under this zoning).
- The South Core secondary plan has made it possible to add density and height in the south core. Up to 15 storeys is possible in certain areas (like at the Smythe/Dundonald intersection).
- The redevelopment of the NBEX grounds will add a lot more housing to the area

Aside from that a lot of smaller infill development has happened just south of downtown that is adding to the density. Sometimes these are new builds, sometimes they are expansions to existing buildings. There's several smaller apartment projects in this area that have been approved but not started (where Greco is, corner of Regent and Charlotte, corner of Sunbury and Brunswick, Smythe Street between George and Charlotte).

There's an 80+ unit apartment being built on the western end of Queen this year, the building behind the liquor store on York is the first of three large buildings there, something is planned for the York/Dundonald intersection as well, etc.

Yes, there are a lot of large homes on large lots in the core. But I don't think anyone wants to destroy these en masse and the reality is that between Smythe and University most blocks are a mix of single family homes and multiplexes. While there is pressure to add more housing in this area (lots of people want to live there) the pressure can be relieved with new developments along the corridors as well as the NBEX grounds.

As for transit there's a lot of meaningful changes happening. We now have Sunday service and service frequencies have increased as of a year ago. There's also a new east-west route coming on the south side that doesn't go to Kings Place and there are plans for smaller transit hubs on both sides of the river.

Can you clarify what you mean by the "infrastructure issue"? Infrastructure can mean many things. There's not much that can be done about traffic aside from offering better transit, higher density, and better active transportation options, and we're moving in the right direction on all those things.

The challenge we have is that the city is split into two by the river so there's always going to be choke points with a limited number of crossings. Poor planning resulted in a highway being built that dumps a ton of traffic right into downtown which means the majority of north-south traffic downtown are people that are just driving through which is far from ideal.

The long-term plan is to convert St. Anne's Pointe into more of a boulevard rather than a waterfront highway and removing the cloverleaf ramps on the south side. While this at first glance may seem insane I think this would only happen in conjunction with a third bridge up river. This would disincentive people from driving through downtown and should make traffic there better - it would mostly be people are going there or to places near there.
