I find it interesting how everyone imagines the taxi industry contributing millions to the City coffers.
City of Calgary's Transportation Livery Services (TLS) is one of the City's few self-supporting business units. TLS exists to regulate the taxi industry and sets the annual fees to the taxi industry to pay for the effort. Total budget is under 3.8 million.
Take a look at the later pages of this recent document:

From the budget projections in the document, it appears that the City nets about a quarter million a year from the taxi industry.
