Abstract
This paper demonstrates that over the 25-year period, 1971-96, the majority of Canadian cities have undergone transition towards an increasingly decentralised urban form. The trends, however, are quite diverse, pointing to fundamental differences in the respective importance of growth in central and outer parts of the metropolitan area. On the whole, the relatively high densities observed in Canadian central cities, in comparison with US ones, appear to reflect residual centralisation rather than continued growth in metropolitan regions' innermost parts. Only Vancouver, and to a lesser extent Toronto and Victoria, exhibit indisputable evidence of post-1971 central-area growth. The predominant trend has been towards suburban-style, low-density expansion, albeit with considerable intercity variation regarding changes in central-area and suburban density. Findings presented here point to previously unidentified trends towards recentralisation in a few CMAs and, in about half of the surveyed metropolitan areas, densification of suburban tracts.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
