The CBC reports that, "Senior Liberals are signalling they're unlikely to use their first opportunity, in early October, to pull the plug on Stephen Harper's minority government."
The "opposition day, on which the Liberals could move a motion of non-confidence in the government, will be sometime from Oct. 1-7."
"Liberal strategists ...note they'll have very little time between Parliament's resumption on Sept. 14 and their first opposition day in which to make the case that they can no longer work with Harper's Conservatives."
That all said, "(Liberal House leader Ralph) Goodale noted the government is bound to provide for a number of opposition days 'at fairly regular intervals throughout the fall' — any of which the Liberals could use to defeat the government."
