The general strike drained much of the vigour from the city's unions. Winnipeg was almost completely free of work stoppages in the eighteen months following the general strike and there were only two walkouts of any significance.
This was the least in many years and shows graphically that workers had had their fill of strikes. A labour force that had expended every possible effort to win a six-week general strike but had been totally defeated was certain to be more docile in the months and years ahead' the workers were simply too exhausted mentally and economically to offer much industrial resistance. The union's vitality was also sapped as a result of the OBU secessionist movement.

It wasn't a total defeat. First, efforts were directed at electing independent labour party people in the municipal election -- which they did.
And second, Winnipeg to this day is a beacon of hope to the labour movement, a time when workers ran an entire damn city themselves successfully -- milk delivered and communal meals served --and challenged the operating of the capitalist state, and it doesn't matter how many times you say “the strikers were not revolutionaries and did not seek the violent overthrow of the existing social and political order” -- not all strikers were revolutionaries but their actions were, and they might not have wanted to meet the Canadian army with weapons, but that also doesn't mean it wasn't revolutionary.
Third, the strike was not about original contract demands, it was about the balance of power between labour and capital, and as the Mather’s Commission and the institution of paternalism in the 1920s demonstrated -- the state and companies had to take serious steps to avoid another such conflagration.
Fourth, the One Big Union was an amazing idea and we lost a great deal when the craft-based unions prevailed.
