Some communities in Ontario procure potable water through water sharing arrangements (WSAs) with other neighbouring communities. This paper explores factors influencing First Nation and municipal participation in WSAs in Ontario. Specifically, we assess whether First Nations communities – many of which suffer persistently poor drinking water conditions – are less likely to be engaged in WSAs than municipalities. We assess this question by applying regression analyses to a unique data set characterizing 419 Ontario communities: 118 First Nations communities and 301 municipalities. Compared to Ontario municipalities, First Nations in Ontario have a lower rate of participation in WSAs. Our regression analyses suggest that community likelihood of WSA participation is strongly associated with factors like geography, regional wealth, and proximity to neighbouring communities with water supply.

安大略省的一些社区通过与其他邻近社区的水共享安排 (WSA) 采购饮用水。本文探讨了影响安大略省原住民和市政参与 WSA 的因素。具体来说，我们评估原住民社区——其中许多社区的饮用水条件一直很差——是否比市政当局更不可能参与 WSA。我们通过将回归分析应用于表征 419 个安大略社区的独特数据集来评估这个问题：118 个原住民社区和 301 个城市。与安大略省市政当局相比，安大略省的原住民参与 WSA 的比率较低。我们的回归分析表明，社区参与 WSA 的可能性与地理、区域财富、
