It’s a fundamental issue that prevents any form of excitement from being discussed, or acted upon:
In Britain, even post-Blair, many of the best and brightest still go into politics. Until the expenses scandal, there was something of a cache to being an MP, something which will probably return in time. The typical Canadian Cabinet is, by comparison, made of poorer quality timbers. The average minister of the crown, here in the Elder Dominion, might make it as a parliamentary secretary back in the Mother Country. Our best and brightest go into business, science and down South. In Canada, those who can’t do, teach, those who can’t teach, teach gym, and those who fail at that run for elected office. There are exceptions. Very few.
The other reason British parties are, relatively, more principled than their Canadian derivatives is national unity. Until about the mid-1990s, no one seriously talked about the break up of the United Kingdom. Even the bleeding ulcer of Ulster was unlikely to be resolved by uniting North and South. This is not the case in Canada. On pretty much every major national issue of the last century and a half — Catholic Schools, prohibition, conscription, foreign policy, Medicare, Afghanistan — English speaking Canada leans one way, and French Canada the other. Raise controversial issues and you might start reminding the Solitudes how much they dislike each other. Thus our national politics has the colour, consistency and firmness of oatmeal. It’s why Mackenzie King, the Great Equivocator, was our longest serving Prime Minister.
