Since his election in 2018, Sol has been a strong advocate of northern Indigenous communities, focusing on access to clean drinking water, environmental justice for Grassy Narrows, and sustainable development in his large northern riding. Sol introduced private members’ bill Bill 76, which would enact the United Nations Declaration on the Rights of Indigenous Peoples into law, as well as Bill 226, Inherent Right to Safe Drinking Water Act, which would mandate the government to provide clean water to all First Nations in the province. As the former lead health advisor for the Nishnawbe-Aski Nation, he worked alongside federal and provincial representatives to transform the way health care is delivered to Treaty No. 9 territory by improving service delivery throughout the riding. Sol is a member of the Kingfisher Lake First Nation and was raised by his family on the land.
