Four members have been Prime Ministers of Canada, 
Sir John A. Macdonald (father of « Canadian Federation » of 1867
but not « Father of Canada » which is Sir Samuel de Champlain in 1608 ), 
Sir John Abbott, 
Sir Mackenzie Bowell (a past « Grand Master » (?)), 
and John Diefenbaker.  
In 1927 the “Orange” movement gave birth to a more intolerant and racist group, the Canadian Ku Klux Klan, which had its deepest roots in small towns in Saskatchewan because of the "yellow peril", but also because of the blacks...Jews...Catholics...
(The “Ku Ku Nest” in the province campaigned against= teaching French + wearing the religious habit + the presence of crucifixes in schools.)
In 1972, there were an equal number of members across Canada.
