<P> Canada had its own version of lend - lease for Britain . Canada gave Britain gifts totaling $3.5 billion during the war, plus a zero - interest loan of $1 billion; Britain used the money to buy Canadian food and war supplies . Canada also loaned $1.2 billion on a long - term basis to Britain immediately after the war; these loans were fully repaid in late 2006 . </P> <P> The Gander Air Base (RCAF Station Gander) located at Gander International Airport built in 1936 in Newfoundland was leased by Britain to Canada for 99 years because of its urgent need for the movement of fighter and bomber aircraft to Britain . The lease became redundant when Newfoundland became Canada's tenth province in 1949 . </P> <P> Most American Lend - Lease aid comprised supplies purchased in the U.S., but Roosevelt allowed Lend - Lease to purchase supplies from Canada, for shipment to Britain, China and Soviet Union . </P> <P> Congress had not authorized the gift of supplies delivered after the cutoff date, so the U.S. charged for them, usually at a 90% discount . Large quantities of undelivered goods were in Britain or in transit when Lend - Lease terminated on 2 September 1945 . Britain wished to retain some of this equipment in the immediate post war period . In 1946, the post-war Anglo - American loan further indebted Britain to the U.S. Lend - Lease items retained were sold to Britain at 10% of nominal value, giving an initial loan value of £ 1.075 billion for the Lend - Lease portion of the post-war loans . Payment was to be stretched out over 50 annual payments, starting in 1951 and with five years of deferred payments, at 2% interest . The final payment of $83.3 million (£ 42.5 million), due on 31 December 2006 (repayment having been deferred in the allowed five years and during a sixth year not allowed), was made on 29 December 2006 (the last working day of the year). After this final payment Britain's Economic Secretary to the Treasury formally thanked the U.S. for its wartime support . </P>

Why did the united kingdom receive so much aid from 1941 to 1944
