Ontario is stronger because of the generations of Italian Canadians who helped build it. Celebrating Italian Heritage Day and the Day of the Italian Republic with the members of @local46 was a powerful reminder of the lasting impact Italian Canadians have had on our communities, our workforce, and our province.  Their stories, values, and contributions continue to unite us and inspire future generations to carry that legacy forward.
