[Q]: passage: Canada first came under British rule with the ((Treaty of Paris which ceded New France, of which Canada was a part, to the British Empire. Gradually, other territories, colonies, and provinces that were part of British North America would be added to Canada. The Royal Proclamation of 1763 enlarged the colony of Canada under the name of the Province of Quebec, which with the Constitutional Act 1791 became known as The Canadas. With the Act of Union 1840 Upper and Lower Canada were joined to become the United Province of Canada. Later, with Confederation in 1867, the British maritime colonies of New Brunswick and Nova Scotia were joined with the British colony of Canada to form the Dominion of Canada, which was subsequently divided into four provinces, Ontario, Quebec, New Brunswick, and Nova Scotia. A number of other British colonies, such as Newfoundland and British Columbia, and large territories such as Rupert's Land initially remained outside of the newly formed federation. Over time, the remaining colonies and territories within British North America came under the control of Canada until the current geographic extent of the country was reached when Newfoundland and Labrador joined Canada in 1949. Although confederation in 1867 led to an enlarged Dominion with increased autonomy over domestic affairs, Canada still remained a colony within the British Empire and was thus subordinate to the British Parliament until the enactment of the Statute of Westminster in 1931. This statute recognized Canada as an independent peer coequal with the United Kingdom, and thus provided the Parliament of Canada with legislative sovereignty over all federal matters except the power to change the constitutional laws of Canada which remained under the purview of the Parliament of the United Kingdom. Canada's final vestige of legal dependence on the United Kingdom was terminated in 1982 with the enactment of the Canada Act, subsequently providing Canada with full legal sovereignty completely independent of the United Kingdom.
 question: was canada ever part of the british empire?
[A]: Yes


[Q]: passage: Computer systems and other electronic devices containing logic circuitry are susceptible to data loss or hardware damage that can be caused by the sudden loss of power. These can include data networking equipment, video projectors, alarm systems as well as computers. To protect computer systems against this, the use of an uninterruptible power supply or 'UPS' can provide a constant flow of electricity if a primary power supply becomes unavailable for a short period of time. To protect against surges (events where voltages increase for a few seconds), which can damage hardware when power is restored, a special device called a surge protector that absorbs the excess voltage can be used.
 question: is power surge the same as power outage?
[A]:
No
