Great article on the bottlenecks to building better apartments in Canada. If you ask a random Canadian on the street they will tell you they want shorter high-rises, taller low-rises, and more livable apartments with cross-ventilation. Yet politicians and policymakers force the opposite.

Quebec has significantly better housing outcomes than the rest of Canada. Language barriers might have helped Quebec not to ālearnā from anglophone Canada š, but also prevent the rest of Canada from learning from Quebec š. Nice to see an English language take on housing from the Quebec perspective!

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.

A key thing that these "nature deserts" analyses often fail to control for is the existence of cities. In this case, first-time buyers tend to be younger, younger people tend to live in cities, cities have less green space per capita, so "first-time buyers are being forced into nature deserts".

Reminds me of the time the City of Vancouver implemented improvements to the pedestrian experience along Point Grey Road, and multi-million dollar homeowners were throwing a fit because the city was clawing back some of their encroachment into public land so it could widen the sidewalk.

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.)

Canāt believe we are still doing this. RM-7 zoning is designed to generate maximally inaccessible townhouses, because not sinking the first floor a metre below ground level would make the building a metre taller and cast an extra 10mins of shade in some SFH zucchini garden. (Also add elevators!)

YIMBYs (like

This is really good to see. It brings predictability to development, not just for developers but also for residents who know what kind of development they can expect to see. Hoping this work will continue and reliance of site-specific zoning will get further reduced.
