In the early years of fisheries canning on the coast, Indigenous peoples did almost all the fishing.
We know there were Métis in the industry along the Fraser River because of the first major strike in the BC fishing industry in 1893. During the strike, Métis in communities along the Fraser River voiced their support for better wages for fishermen, and were subsequently arrested and charged with so-called "lawlessness".
The backstory was that Hon. J. H. Turner, a provincial Minister of Finance, himself a canner with business interests on the Fraser River, wired the Premier asking for police to be sent. Half-breeds were arrested and charged with "intimidation"!
These "arrests" were wrongful as the cases were adjourned repeatedly by prosecutors until the strike was over and then the charges were quietly dropped!
