Maximum tariff
The published figures are maximum regulated meter rates. TaxiRates uses them for the estimate and labels the result accordingly rather than implying every operator must charge exactly that amount.
Regional scope
The supported region includes Kitchener, Waterloo, Cambridge, Woolwich, Wellesley, Wilmot, North Dumfries and Breslau. Out-of-region trips are not extended blindly.
Using the regional maximum correctly
The published Waterloo Region figures are maximum taxi rates, not a promise that every licensed operator will charge the maximum on every trip. TaxiRates uses the maximum schedule as the defensible ceiling for the estimate and labels it accordingly. Waiting time matters when the meter is in its time-based mode; it is not added as a second full charge to every moving kilometre.
Waterloo International Airport (YKF) is handled within the same regional licensing framework. For trips that clearly leave Waterloo Region, the calculator does not continue the regional maximum into another jurisdiction without an applicable fare rule.
