Final answer:
Section 91 grants the federal parliament enumerated and residual powers, with enumerated powers specified in the Constitution and residual powers implied.
Step-by-step explanation:
Under section 91 of the Canadian Constitution Act, 1867, the two powers granted to the federal parliament are enumerated and residual powers. The enumerated powers are those specifically listed in the Constitution that set out the jurisdictional boundaries within which the federal government has authority, while the residual powers are those that are not specifically listed but fall under federal jurisdiction by default. These ensure that the federal government can operate effectively, both at home and abroad, having authority over matters like taxation, defense, and commerce.
