Today is not only the first day of summer, it is also National Indigenous Peoples Day.
National Indigenous Peoples Day is a day recognizing and celebrating the cultures and contributions of the First Nations, Inuit and Métis Indigenous peoples of Canada.
The day was first celebrated as National Aboriginal Day in 1996, after it was proclaimed that year by then Governor General of Canada Roméo LeBlanc, to be celebrated annually on June 21.
This date was chosen as the statutory holiday for many reasons, including its cultural significance as the Summer solstice, and the fact that it is a day on which many Indigenous peoples and communities traditionally celebrate their heritage.
It was renamed from National Aboriginal Day in 2017.
