Calgary vs Ottawa
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Calgary leads on any axis where its bar is higher, Ottawa where its is. The cost bar uses a higher-is-cheaper scale, so Ottawa's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Calgary | Ottawa |
|---|---|---|
| Livability | 59 | 57 |
| Cost (higher=cheaper) | 44 | 45 |
| Climate | 65 | 62 |
| Safety | 68 | 64 |
| Summer °C | 16.2 | 20.4 |
| Winter °C | -9.8 | -11.1 |
| Top disaster risk | extreme cold / winter | extreme cold / winter |
Calgary vs Ottawa: the short answer
Calgary comes out ahead on overall livability (59/100), only marginally above Ottawa (57/100). The two cities diverge most on natural-disaster exposure. On affordability Ottawa is the cheaper base — nearly identical prices on our cost index (Calgary 44 vs Ottawa 45, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Ottawa runs warmer in summer (about 20.4°C peak vs 16.2°C in Calgary), while winter lows sit near -9.8°C in Calgary and -11.1°C in Ottawa. On natural-disaster exposure Calgary is the safer choice (safety 68/100); the dominant modelled hazard is extreme cold / winter for Calgary and extreme cold / winter for Ottawa.
Which city should you choose?
- On a tight budget → Ottawa — lower everyday costs..
- You want warmth → Ottawa — hotter summers.
- Safety is the priority → Calgary — lower disaster risk.
- Best all-rounder → Calgary — highest overall livability.
Data & methodology
Cost scores are normalised from World Bank price-level data. Climate figures (summer highs, winter lows) are drawn from 1991–2020 climate normals. Disaster-safety blends USGS earthquake history (magnitude 4.5+ within 300 km since 1980), tropical-cyclone basin position, flood/elevation exposure and Köppen climate zone. The livability score is the weighted composite of cost, climate and safety. All figures are planning indicators for 2026, not guarantees — verify specifics before relocating.
