Ontario's revised water and sanitation legislation has triggered alarm among policy experts who warn the changes create pathways for private corporations to assume control of public water infrastructure through arms-length entities.

The law establishes mechanisms that allow municipalities to delegate water management responsibilities to quasi-independent corporations operating outside direct democratic oversight. These arrangements bypass traditional public accountability structures, critics argue, leaving communities with limited recourse over rates, service standards, and operational decisions.

Such governance models historically correlate with increased water costs for consumers. Private and semi-private water operators have documented track records of raising tariffs substantially after taking operational control, particularly in systems serving lower-income populations with reduced bargaining power.

The legislation does not explicitly prohibit full privatization. Instead, it creates legal scaffolding for incremental transfers of control to corporate entities that operate under different regulatory frameworks than publicly managed utilities. Once these entities gain operational authority, reversing privatization becomes politically and financially difficult.

Water advocates note Ontario's move mirrors patterns across North America. Cities including Toronto have resisted similar proposals, while jurisdictions including parts of the United States have struggled to reclaim water systems after privatization agreements became entrenched in contracts.

Public water systems in Ontario currently serve 12 million residents and operate under direct municipal or regional control. Shifting governance to arms-length corporations risks fragmenting these networks into patchwork systems where profit motives rather than universal access principles guide investment and rate-setting.

The law does not mandate private control but removes legal barriers that previously protected public operation. Environmental groups and labour unions have called for amendments that would explicitly preserve public ownership and democratic governance of water infrastructure.
