No Direct Taxi from Ottawa to Montreal: Take the Train or Bus Instead

There is no standard taxi or ride-hail service operating the ~200 km (125 mi) intercity route between Ottawa, ON and Montreal, QC. The fare would be prohibitive (~$300–$500+ CAD) and drivers generally won't accept cross-province deadhead returns.

Real Options (Ottawa ↔ Montreal)

Recommendation

VIA Rail is the gold standard: city-center to city-center, productive time, reliable. Bus is the budget king. Drive only if you need a car in Montreal. Forget the taxi.
