The minister, in the minister's absolute discretion, may issue the licences to which reference is made in this regulation and renewals thereof. Despite any other provision of this regulation, a person is entitled to a licence referred to in the Act or in this regulation if the person (a) submits a completed application form; (b) pays the applicable fees according to the Table of Fees set out in the Schedule; (c) holds a certificate, registration, licence or other form of official recognition issued by a regulatory authority in another Canadian jurisdiction that, in the minister's opinion, authorizes the person to install and service substantially the same oil burning equipment or gas burning equipment, or both, as the holder of that type of licence issued under the Act or this regulation is authorized to install or service; and (d) provides evidence satisfactory to the minster that the person who holds the certificate, registration, licence or other form of official recognition referred to in clause (c) is in good standing with the issuing regulatory authority. Subject to subsection (5), no person shall install or service oil burning equipment unless that person has first passed the examination prescribed by a board, and is the holder of a subsisting licence that has been issued by the minister and is in a form set by the minister. A person may apply for a licence to be issued under this regulation if that person has (a) two years' experience in the installation and servicing of oil burners and equipment under the direct personal supervision of a licensed installer; or (b) completed an apprenticeship in a related trade and has had six months' continuous experience in the installation and servicing of oil burners and equipment under the direct personal supervision of a licensed installer. No person shall sell or deliver fuel oil for use within the province in a fuel oil burner used for heating purposes unless the fuel oil meets the requirements for the supply of fuel oil set forth in CSA B139-15, Installation Code for Oil-Burning Equipment, as amended from time to time. No person shall, within the province by himself or herself, or by a clerk, servant, employee, or agent sell or offer for sale, or deliver or install in any premises, oil burning equipment that is not approved. The minister may prohibit the use, for heating purposes within the province by any person, of oil burning equipment that the minister, decides is unsafe. No person shall (a) install an oil burner or fuel oil tank; or (b) make any alteration of, or addition to, an oil burner; without first applying for a permit from the minister to make the installation, alteration, or addition, except that normal servicing and maintenance of an installed oil burner does not constitute the making of an alteration or addition thereto, for the purpose of this subsection. An emergency shutdown system shall be installed in any tank system supplying propane to a direct-fired vaporizer. The emergency shutdown system shall be of the electrical, pneumatic or mechanical type, or a combination of them, and the means to activate the emergency shutdown system shall be located at least 7.6 m (25 ft) from the direct-fired vaporizer(s). When activated, the emergency shutdown system shall initiate shut-off of the liquid line at the tank location that is connected to the vaporizer. There are the following five classes of licences for gas fitters, namely: (a) commercial and industrial gas fitter's licence; (b) domestic gas fitter's licence; (c) liquid petroleum gas fitter's licence; (d) utility gas fitter's licence; and (e) special gas fitter's licence. A person holding a commercial and industrial gas fitter's licence may install any gas equipment. To obtain one of the five classes of licences set out in section 13, a person must (a) submit a completed application form; (b) pay the applicable fees according to the Table of Fees set out in the Schedule; and (c) meet the qualifications for the applicable class of licence, as set out in subsection (2).
