Certainly, sir, I could provide the graph and the sources for the data, which came from Industry Canada and from Statistics Canada. It is in a way interesting and ironic that Canada's exports have declined so dramatically as a share of our GDP over the last decade, which is precisely the timetable during which our exports of unprocessed or barely processed petroleum products expanded so dramatically. We are exporting more petroleum. Petroleum exports as a share of our GDP have increased by about two percentage points, as I mentioned.
But the decline in exports of virtually everything else that we produce, other forms of merchandise.... Tradable services, as I mentioned, have declined as a share of GDP. Our tourism has declined dramatically as a share of our GDP. Those outweigh the increase in our exports of petroleum by a ratio of about 6:1. The overall net impact on our trade performance has been very negative. We are one of the few countries in the world that export less as a share of our GDP than we did 10 years ago. This seems to go counter to the idea that we're living in a more globalized economy.
The impact is that we have shifted a larger proportion of our work and capital inputs from tradable sectors to non-tradable sectors, in particular private services, but to some extent public services, which have been less affected by the impact of the resource boom on the currency. We have more production and employment in sectors where Canadians are producing for other Canadians, which isn't all bad, but there are implications of that for our productivity performance and for our trade balance. Our exports have declined; our imports have not declined proportionately, and in the course of exporting all of these non-renewable resources, we've actually seen our trade balance and our current account balance deteriorate dramatically. Canada's current account deficit today is about 4% of GDP. That's a very large and worrisome trade current account imbalance. It contributes to growing international indebtedness by Canada and is something that reflects the deindustrialization that is an unintended side effect of the resource boom.
