CHAPTER III 
THE SOURCES OF THE LAw AND CUSTOM OF THE 
CONSTITUTION. 
THE legal rules and constitutional customs that form the 
« Constitutional Law and Custom” of Canada are derived 
from seven sources:—(1) Imperial Acts, (2) Dominion Acts, 
(8) Provincial Acts, (4) Orders in Council issued under Im- 
perial, Dominion or Provincial authority, (5) Orders and rules 
of the Dominion Parliament and of Provincial Legislatures, 
(6) Usages, and (7) The Letters Patent, Commission and 
Instructions issued to the Governor-General. 
1. Imperial Acts. Though the Union Act of 1867 con- 
tains the general scheme of the Constitution it has been 
supplemented by several subsequent and important statutes. 
The 34 & 35 Vie. (i) c. 28 conferred on the Dominion 
power to establish new provinces and to provide for the 
government of any territory not within the limits of a 
province, 
The 38 & 39 Vic. (i) c. 38 repealed the 18th section of 
the Act of 1867 relating to the privileges of the Dominion 
Parliament and more clearly defined the powers of the legis- 
lature to determine its own privileges, and the 49 & 50 Vic. 
(i) c. 35 authorized the Canadian Parliament to make pro- 
vision for the representation of new provinces in the Senate 
and House of Commons.
