1905; Saskatchewan and Alberta
No constitutional guarantee was given to French Catholic minority of these new provinces, while the federal government did not show no will to protect these rights, any more than it did at school conflicts in New Brunswick and Manitoba. 
The « School Act » of Alberta imposed English as the ONLY language of instruction.

In Saskatchewan, the « School Act » of 1909 made English the ONLY language of instruction, but allowed limited use of French in primary schools.

(1929; a third law of Saskatchewan yet abolished the French in schools that Act adopts the 1918 and shed.)
