Canada's annexed Regulations Respecting Reduction in the Release of Methane and Certain Volatile Organic Compounds (Upstream Oil and Gas Sector) published in the Canada Gazette, Part II, on April 26, 2018 requires implementation of Leak Detection and Repair (LDAR) programs at Canadian onshore upstream oil and gas facilities amongst other requirements. An onshore upstream oil and gas facility is a facility containing stationary equipment that are located on a single site, on contiguous or adjacent sites or on sites that form a network in which a central processing site is connected by gathering pipelines with one or more well sites - for the purpose of:

  1. The extraction of hydrocarbons from an underground geological deposit or reservoir;
  2. The primary processing of those hydrocarbons; or
  3. The transportation of hydrocarbons - including their storage for transportation purposes - other than for local distribution.

They include a gathering pipeline, transmission pipeline, natural gas gathering and boosting station, natural gas transmission compressor station and natural gas processing plant.

Summary of Requirements for On-Shore Upstream Oil & Gas Facilities

The regulations' requirements cover key fugitive and venting emission sources in the upstream oil and gas sector as described below. The complete regulation can be found here.

Emission SourceRequirements
Fugitive (leaks)
  • Implementation of a leak detection and repair (LDAR) program
  • Inspections for leaks three (3) times per year
  • Corrective action when leaks are found
  • Date of implementation: January 1, 2020
General facility production venting
  • Venting limit of 1,250 m3 of natural gas per month (15,000 m3 per year)
  • Conservation of natural gas for re-use on site or for sale, or flaring/clean incineration of natural gas
  • Date of implementation: January 1, 2023
Venting from pneumatic devices
  • Venting limit of 0.17 m3 of natural gas per hour for pneumatic controllers
  • Conservation of natural gas for re-use on site or for sale, or replacement with non-emitting or low-bleed pneumatic device
  • Date of implementation: January 1, 2023
Venting from compressors
  • Annual measurements of emissions of natural gas from compressor vents
  • Corrective action when emissions are higher than the applicable limit
  • Date of implementation: January 1, 2020
Venting from well completions involving hydraulic fracturing
  • No venting
  • Conservation of natural gas for re-use on site or for sale, or flaring/clean incineration of natural gas
  • Date of implementation: January 1, 2020
