The city's taxi union, Unifor, will take its battle against Uber to the courts next week on two fronts.

First, Unifor lawyers will seek an injunction to stop the unregulated digital ride-sharing company from doing business with customers in Ottawa.

"Hopefully a judge will look at (the proposed injunction) and say this is an illegal operation and they should be prevented from operating," said Harry Ghadban, regional director of Unifor in Eastern Ontario.

Part II of the planned offensive on the digital ride-sharing service is a lawsuit against not only Uber, but also its drivers.

"(Uber) Drivers keep 80% of (driving fares) and we think they're both doing something wrong and that most of that money belongs to our people," said Amrik Singh, the local union boss.

Uber collects just 20% of fares paid by customers.

The City of Ottawa is trying to figure out how to best regulate taxis, limousines and ride-sharing services such as Uber. But taxi drivers aren't interested in waiting.

Singh said the lawsuit will seek damages for every cab driver who has lost fares. He said it's too early to say how much the union's lawyers will be trying to get out of Uber.

The lawsuit, he said, will likely be filed mid-way through the week.

Meanwhile the city's taxi dispatcher, Coventry Connections, is floating a new contract proposal to locked-out Airport Taxi drivers which could see a major remodelling of the way the city delineates turf for competing cab companies.

The current model is supposed to allow an exclusive "stand" for the airport fleet.

"His proposal is very confusing," said Ghadban, but he said it is a first strp to the city's ongoing taxi labour strife, which has been continuing since the summer.
