Thanks for all your suggestions. I was near Produce Depot on Carling today so I stopped in and bought fresh okra there. I also bought file powder at Chilly Chili's at Bayshore.
Produce depot has them consistently fresh. I have seen them in food basic a few times frozen when I was looking for the soup filled steam buns for mom.
Fresh Okra is available at the South Asian food market in the little mall behind Vaishali's Indian store on Carling. They get fresh supplies every Friday.
