Electric and Magnetic Fields

Work and Position of Hydro-Québec

Hydro-Québec has helped to advance knowledge about EMFs through its own research. It has conducted a number of studies with universities, Health Canada and other power utilities, including Électricité de France, Ontario Hydro, BC Hydro and the Bonneville Power Administration in Portland, Oregon.

Corporate Position on EMFs

Although the health impacts of EMFs have never been confirmed, Hydro-Québec has made a commitment to be vigilant and prudent with respect to EMFs and their possible health effects. The company has also adopted a corporate position on EMFs. [PDF]

  • A study of optical detection of microtremors in workers exposed to alternating magnetic fields is being conducted by the Université de Montpellier in France with the support of Hydro-Québec and Électricité de France.

    The objective is to understand the interaction between MFs and the nervous system, as this interaction is used by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the Institute of Electrical & Electronics Engineers (IEEE) to establish exposure limits.
