I, personally, am less worried about Canada. Remember, please, that Michael Ignatieff was speaking to Americans in America and so he was, mainly, addressing the partisan gridlock that, currently, characterizes the US Congress ~ the Americans have a well crafted system but it was designed to be easy to not do things, it was, intentionally, designed to be different from the one in London which had, and still has, a much more subtle set of checks and balances. Our, Westminster system, is revolutionary (government's can be, quite summarily, turfed from power) and responsible - the government/executive (cabinet) is responsible to parliament, parliament, in its turn, answers to the people. The US Constitution provides a stable, predictable and, above all, representative government. Our system - even during the Gladstone-Disraeli "clash of the titans" (as a TV series described it) - was able to do its business in a generally efficient manner because the system worked, the government governed, for the common weal, despite the mighty struggles of two powerful antagonists. The US system is less robust, it is more easily shifted into 'stall,' and that is what I think Ignatieff fears.
