Mary Anne Caibaiosai completed her four year commitment to walk the length of the Grand River from its source near Dundalk, to the mouth of the river in the Dunnville and Port Maitland area at Lake Erie and then back. The All Nations Grand River Walk started out in 2018. Caibaiosai started out leading a core group of people that grew to a larger group for the two week journey that September. Each year, more people have joined the walk where they've met people in various communities who wanted to know more about what the group was doing.
