Impact verdict

Medium impact. MEDIUM: Severe pluvial/urban flooding affected multiple Quebec locations including Canada's second-largest metropolitan area, with residents reporting total loss to residential properties and ~150 mm of rainfall noted in reporting. However, no insured loss estimate is provided, no named commercial or industrial asset impact is identified, no specific infrastructure damage details are available, and the flood mechanism (pluvial/urban vs. riverine) remains unspecified, limiting insured-loss visibility for London Market specialty books. No article content was fetch-verified under WP-C1 GKG hardening, so claims are grounded in metadata themes and amounts only.
