The agency says this put Canada into a net asset position of $26.7 billion.
It says the decline in net debt was attributable to relatively stronger foreign equity markets and a weaker Canadian dollar, which raised the value of Canada's international assets more than it increased the value of international liabilities.
During 2013, Canada's overall net international investment position increased by $328.8 billion, despite an ongoing current account deficit.
Canada's net foreign indebtedness with the United States decreased by $176.4 billion to $280 billion at the end of 2013.
At the same time, Canada's net asset position with the aggregate "other countries" increased by $152.4 billion to $306.7 billion.
