The short answer
Choose React Native if you have a web team, a JavaScript or TypeScript codebase, or need to share logic with a web app. Choose Flutter if you want pixel-identical UI on both platforms, heavy custom animation, or your team already writes Dart. For most Canadian business apps, either works and the decision is about people.
How they compare in practice
- Performance: both are close to native for business apps; Flutter has an edge on complex custom UI, React Native on integrating native modules.
- Ecosystem: React Native has the larger library and hiring pool; Flutter has more consistent first-party tooling.
- Platform look: React Native uses native components; Flutter draws its own, which is a feature or a bug depending on the brief.
- Web sharing: React Native shares more naturally with React web apps.
Hiring in Toronto, Calgary and Vancouver
React Native developers are easier to find in all three cities because the JavaScript pool is deeper, and Calgary in particular has a strong React community around the energy and logistics sectors. Flutter talent is growing, especially in Vancouver, but is thinner. If you plan to build an in-house team later, that matters.
Which to pick for your project
- Web app exists or is planned: React Native.
- Brand-heavy consumer app with custom UI: Flutter.
- Lots of native integrations (Bluetooth, background services): React Native, slightly.
- Small team maintaining it for years: whichever matches their existing skills.
