Why was it weaker than the case in the US that failed?

The case in the US alleged that Sirius XM in California had collected the Plaintiffs and putative class members’ driver’s license information and VIN’s along with contact information including name, phone number, and address. In Canada, the disclosure we received in regard to the Representative Plaintiff only had personal information that was already in the public domain, in particular name, address, phone number and type of vehicle. It also included the satellite radio model number.
