Stay clear, stay safe, stay distanced this August long weekend

Always evaluate water conditions and be prepared

Toronto – As cities and towns across the province are reopening their communities, Ontario Power Generation (OPG) wants to remind you to take extreme caution and exercise sound judgement this August long weekend when around water, especially around our hydroelectric stations and dams.

“Your safety is of the utmost importance to us at OPG. We ask that you take great care when enjoying yourselves in and around waterways this weekend,” said Mike Martelli, OPG’s President of Renewable Generation. “Whether you’re boating, swimming or fishing, conditions can change quickly and without warning.”

The waterways near OPG’s facilities are not a safe place for recreation. Before participating in any outdoor water recreational activity, OPG is advising the public to first visit: www.opg.com/watersafety.

Despite continued warnings, some people disregard our signs and barriers, putting themselves at risk. OPG works with the Ontario Provincial Police to enforce these warnings, and charges can - and have - been laid.

“Your safety is of the utmost importance to us at OPG. We ask that you take great care when enjoying yourselves in and around waterways this weekend."

Mike Martelli, OPG’s President of Renewable Generation

OPG operates 66 hydroelectric stations and 241 dams on 24 river systems throughout Ontario.

Activities on the water can be lots of fun when done safely. Enjoy the August long weekend, the unofficial mid point of summer. Remember to stay clear, stay safe and stay distanced!

OPG is the largest electricity generator in the province, providing almost half the power Ontarians rely on every day. It is also one of the most diverse generators in North America with nuclear, hydro, biomass, solar and gas assets.

Longue fin de semaine du mois d’août : plus loin, plus sûr

Évaluez les conditions de l’eau et soyez prêts à parer à toute éventualité en tout temps

Toronto – Alors que les collectivités des villes à travers la province reprennent leurs activités, Ontario Power Generation (OPG) souhaite vous rappeler d’être toujours extrêmement prudents et de faire preuve de bon sens pendant cette longue fin de semaine du mois d’août lorsque vous vous trouvez aux abords de l’eau, et plus particulièrement aux abords de nos centrales hydroélectriques et de nos barrages.

« À OPG, votre sécurité est au cœur de nos priorités. Nous vous demandons d’être très prudents cette longue fin de semaine, lorsque vous serez aux abords des voies navigables ou dans l’eau, a déclaré Mike Martelli, président, Production d’énergie renouvelable d’OPG. Que vous partiez naviguer, nager ou pêcher, les conditions peuvent changer brusquement, sans signes annonciateurs. »

Les voies navigables aux abords des installations d’OPG ne sont pas des lieux récréatifs sûrs. Avant de participer à toute activité récréative extérieure sur l’eau, OPG conseille au public de se rendre tout d’abord sur le site www.opg.com/watersafety.

Malgré nos avertissements constants, certaines personnes ne tiennent pas compte des panneaux et des barrières d’OPG, se mettant ainsi en danger. OPG travaille de concert avec la Police provinciale de l’Ontario pour faire respecter ces avertissements, et des accusations peuvent être – et ont été – portées.

OPG exploite 66 centrales hydroélectriques et 241 barrages sur 24 rivières en Ontario.

Les activités sur l’eau peuvent être très amusantes lorsqu’elles sont réalisées de manière sécuritaire. Profitez bien de la longue fin de semaine du mois d’août, laquelle correspond à la date non officielle marquant le milieu de l’été, mais n’oubliez pas de rester plus loin et de garder vos distances, c’est plus sûr.

OPG est le producteur d’électricité le plus important de la province; il produit près de la moitié de l’électricité pour satisfaire les besoins quotidiens des Ontariens. C’est également l’un des producteurs d’électricité les plus diversifiés en Amérique du Nord, spécialisé en énergie nucléaire, hydroélectrique et solaire, ainsi qu’en bioénergie et en gaz.
