Brake Job 2017 Nissan Rogue - Oakville or Mississauga, ON

While at a Nissan dealership in Oakville for service, I was told the brakes on all 4 wheels were down to 3 mm and I needed to replace pads and rotors on all 4 wheels at the earliest. I have been quoted an exorbitant amount by the dealership. Are there any other reliable and cheaper garages for this job in Oakville, Burlington or Mississauga?
