Des orages ont causé inondations et pannes de courant, lundi, à Toronto. Quelque 300 000 abonnés de Toronto Hydro étaient privés de courant en début de soirée.

À Mississauga, environ 80 % des abonnés d'Enersource étaient privés d'électricité.

Ces précipitations ont transformé l'heure de pointe en cauchemar pour plusieurs automobilistes, mais aussi pour les usagers du métro, puisque tout le réseau souterrain a été immobilisé en raison des problèmes de courant. Une dizaine de stations ont dû être fermées. La police demande aux automobilistes d'être prudents, car plusieurs feux de circulation ne fonctionnent plus dans la grande région de Toronto.

Selon Environnement Canada, pas moins de 75 millimètres de pluie étaient attendus tandis que la ligne orageuse se déplaçait de Mississauga et Brampton vers Markham, Richmond Hill et Toronto.

« Certains secteurs ont déjà reçu plus de 90 millimètres de pluie et devraient en recevoir au total de 100 lorsque la tempête sera terminée en fin de soirée », peut-on lire dans un avertissement émis par Environnement Canada.

Des portions des autoroutes 427, 401 et 27 ont été fermées en raison des inondations.

Le transporteur aérien Porter a annulé tous ses vols en provenance ou en partance de la Ville-Reine.

Sur Twitter, le maire de Toronto Rob Ford demandait à ses concitoyens de demeurer prudents.

« Nous surveillons la situation de très près. Des équipes ont été déployées partout dans la ville. Veuillez éviter les zones inondées », conseille le maire.

L'hôtel de ville a d'ailleurs été évacué.
