A little googling leads to the Battle of the Belly River entry. At the end of the discussion on this battle it states:
In 1890, the town of Lethbridge was founded near the battle site. The battle itself is commemorated in Indian Battle Park.
More information can be found at the City of Lethbridge website:
Much of the battle took place in Indian Battle Coulee on the west side of the river, while the retreat across the river ended in a last stand close to the Coal Banks Interpretive Site.
So the city apparently has markers at least recognizing sites concerning the battle.
The Cypress Hills Massacre website has the following concerning the site:
The site of the massacre was designated a National Historic Site of Canada in 1964.2 Artifacts from the Cypress Hills Massacre have also been preserved at nearby Fort Walsh National Historic Site, along with reconstructions of Farwell's and Solomon's trading posts.
