Still thinking about this part of the conversation, showing a poster by @tomflood.bsky.social next to two by Klaus Staeck that I remember from my childhood.
Lots of parallels between discussions in Germany (and other places in Europe) back then and Canada (and the US) 30 to 40 years later.

Late Halloween news, StatCan continues to report long-term declines in paranormal activity in homes across Canada. *

Scissor stairs in my lowrise (5 storey) condo built in 2009. Feels like slightly more efficient layout with stairs tucked behind the elevators.

Check-in on the latest NRCAN LIDAR-derived 3D building data. Their automatic detection is still quite coarse, some buildings are missing, some get footprint very wrong, other mess up on height. And failure to deal with buildings with sections of different heights.
Looking forward to next iteration.

This has got to be a joke. It’s a giant red flag screaming for help, how can you write something like this down and then hit publish…

In case you were eagerly awaiting the introduction of an internet-connected device to monitor and analyze your human waste, I got good news for you.
If not, just carry on and continue to enjoy your sittings without constantly worrying about the firmness or colour of what you are flushing down.

Morning radio talking about people driving down to the Jays game, squinting hard there may have been a slight increase in southbound car traffic at the Peace Arch crossing yesterday compared to weekly patterns in the last couple of weeks.

But if we broaden our view and not take for granted who lives together in a given dwelling unit and ask ourselves how much housing is needed so that each family unit gets to enjoy the privacy of having own home, not just their own bedroom, then we really see the scale of the housing problem.

hat type of crowding looks at (the extreme end) of people lacking the privacy of their own bedroom. The typical crowding metric at the bedroom level that we use is NOS, which gives some indication of people sharing bedrooms. Here we are seeing much higher shares.

Quick check-in with Canadian data. Canadian PUMF top-codes at 7+ people in a household, so not quite same metric.
(And some caution is advisable when drilling into scenarios like this where coding errors and other data quirks can accumulate. Even when checking across replicate weights.)

“How can you just falsify data?” — Very easily apparently. And UBC does not seem to feel the need to let the public know about this.

Workday morning rush hour for comparison. More bus lines, and more service.
(Still missing buses not sending realtime data, as well as sea bus and skytrain which don't show up in the realtime data feed.)

Finally got around to playing with TransLink realtime GTFS data. Kind of fun. Transit in Vancouver is looking pretty good, especially considering this is an hour midday on a holiday weekend, with some lines not running (hello 44) and not all buses reporting real-time information.

September data was released today. The drop in absolute number of travellers is a bit lower than in the (higher volume) summer months, but year over year percentage change drop held fairly steady.

Net international migration was slightly positive in Ontario, but not enough to pull Ontario net migration out of the negative. It's important to note the different roles of immigration and net NPR for those last two graphs, these are very different processes.

Adding in international migration gets interesting for BC, in Q2 2025 international migration was negative, pulling overall net migration into negative territory. (And total population growth in BC was slightly negative too in Q2.)

On the flip side, Alberta and Nova Scotia have been seeing (net) interprovincial inflows. Inflows in Nova Scotia slowed a bit but it's still going strong, Alberta is off its peak but still at very high net inflows.

Ontario and Quebec continue to see net inter-provincial outflows. For Quebec it's (almost) always been that way, Ontario did have a 5-year period of net inflows in the second half of the 2010s but generally also experienced outflows. Although not as much as recently.
