The Edmonton Taxi Association is gearing up to take Uber to court.

Drivers and taxi owners will initiate legal proceedings against Uber, "seeking injunction and compensation for the losses and damages" caused to the taxi industry, association president Jasbir Gill said.

Gill said other parties, including the city, could be named in the lawsuit.

"We are not making enough money to maintain service," Gill said. "We are really worried, because we are law abiding, regular taxis."

The Court of Queen's Bench denied the City of Edmonton's temporary injunction filed against Uber on April 1, saying the application was poorly targeted. The city applied for a permanent injunction and is waiting for a court date.

Gill said the city's injunction application was disappointing and negligent, and that the city has failed to enforce its vehicle-for-hire bylaws. The association is also pushing for an inquiry into how the injunction failed.

Taxi drivers are organizing a rally at city hall on April 28 to demand stricter enforcement against the ride-share company.

Meanwhile, more than 12,700 people have signed an online petition to keep Uber in Edmonton, and the company claims to be on track to create the equivalent of more than 2,000 full-time jobs in the city by the end of 2015.

Uber is pushing the city to update its vehicle-for-hire regulations to accommodate technology-driven services. Council passed a motion in January requiring Uber to stop charging for rides in Edmonton until it can draw up new legislation, which likely will not happen until fall.
