* Canadian dollar losing streak extends to 7th session
* Housing data comes in weaker than expected
* Bond prices finish lower after early gains squandered

TORONTO, Aug 11 (Reuters) - The Canadian dollar opened the week with a lower close versus the U.S. dollar on Monday as the slide in oil prices rattled the commodity-linked currency, which has fallen in all but one session in the past three weeks.
Bond prices ended lower across the curve as the slide in the U.S. Treasury market spilled north of the border and wiped away gains recorded early in the session after weak Canadian housing starts figures.
The Canadian dollar closed at C$1.0693 to the U.S. dollar, or 93.52 U.S. cents, down from C$1.0674 to the U.S. dollar, or 93.69 U.S. cents, at Friday's close.
For the past few weeks the Canadian dollar has been unable to shake off a funk caused by a combination of a stronger U.S. dollar, concerns about global growth and a sharp drop in oil prices from last month's record high above $147 a barrel.
"The downward pressure is still there," said Paul Ferley, assistant chief economist at Royal Bank of Canada. "A generally stronger U.S. dollar, with the catalyst being abetted by further weakening in oil prices, is doing the driving."
Early in the session the Canadian currency had rallied to a high of C$1.0645 to the U.S. dollar, or 93.94 U.S. cents, and after losing 3.8 percent last week it appeared ready to end a seven-session losing skid.
Canadian trade data due out on Tuesday is expected to show the country's trade surplus widened to C$5.80 billion in June from C$5.54 billion in May, according to analysts surveyed by Reuters.
Figures that have been released in recent weeks have pointed to a slowing economy, including gross domestic product and jobs data that both missed estimates.
The latest piece of Canadian data, released on Monday, showed Canada's housing market continued to cool over the summer. Housing starts fell 14.8 percent in July from June.
BOND PRICES LOWER
Bond prices were boosted early by the housing data, but the gains trickled away as the session wore on since a rally in U.S. equities shook bonds there and influenced dealers north of the border given the lack of any key events.
"It seems bond markets are being buffeted by what's happening with equities," said Ferley, who said the U.S. CPI data due out on Thursday will be a key factor in deciding where bond prices are heading.
The two-year bond fell 6 Canadian cents to C$101.74 to yield 2.750 percent. The 10-year bond dropped 12 Canadian cents to C$105.05 to yield 3.632 percent.
The yield spread between the two-year and 10-year bond was 105 basis points, down from 109 basis points on Friday.
The 30-year bond fell 1 Canadian cent to C$115.99 for a yield of 4.054 percent. In the United States, the 30-year treasury yielded 4.607 percent.
The three-month when-issued T-bill yielded 2.49 percent, down from 2.48 percent at the previous close. (Editing by Peter Galloway)
