Ternary Plot Showing Change in vote share between 2021 and 2025 election (Liberal / Conservative / Other)

Data: Canadian Election Study

Interpretation :

• Younger Voters (Blue/Darker Lines): Show a strong shift away from "Other" parties, moving primarily downward toward the main establishment options, and a bit left toward liberals
• Middle age voters, light blue and green moved down away from "Other" and split roughly equal between liberal and conservatives.
• Older Voters (Red/Orange Lines): Moved strongly toward Liberals from both conservative and Other

Data: Statistics Canada, Table 35-10-0177 (police-reported crime severity/incidents by CMA). Tools: R, ggplot2 (mixed-effects modeling via lme4/arm).

Police-reported crime data across Canadian census metropolitan areas from 1998–2025, showing which offense categories are trending up or down over time.

Chart 1 : Long-term trend by city (mixed-effects model)
Estimated relative rate of change per CMA, where 0 = no net shift over the period. Red = upward trajectory, blue = downward. This isolates the direction of change in an typical city rather than raw volume.

Chart 2 : Category breakdown over time
Incidents per 100,000 population, faceted by offense category. Grey lines = individual CMAs, solid line/band = national median and interquartile range, dashed line = national average.

• Rising: extortion, online/cyber-related exploitation, fraud, and shoplifting all show marked increases post-2015/2020 across most CMAs.
• Falling: traditional property crimes — breaking & entering, motor vehicle theft, theft under $5,000 — show multi-decade declines since the early 2000s, despite some recent upticks.

A note on interpretation: this is police-reported data, so shifts can reflect actual changes in criminal activity, but also changing legal definitions, new digital reporting channels (e.g., online fraud reporting tools), shifting police enforcement priorities, and changes in public reporting behaviour over time.
