  Ontario's electricity system is made up of three components: Generation, Transmission and Distribution.

  Generation

  Generators across the province produce electricity, primarily through nuclear, natural gas, water, wind or solar. They are owned by Ontario Power Generation and a number of private companies.

  Transmission

  Hydro One owns the high voltage transmission lines that carry electricity from generators across the province.

  These lines bring electricity from the generators to distribution companies throughout the province.

  

  
  

  Distribution

  Distribution companies, like Halton Hills Hydro, step down the voltage to levels that homes and businesses can use and distribute that electricity to their customers.

  Halton Hills Hydro distributes electricity to the homes and businesses within the Town of Halton Hills.
