Certainly.
The tangible contributions to Canada would refer to economic contributions that are made by these Canadians. I mentioned the chambers of commerce, the local business councils that are in virtually every major city of the world, that are working hard to promote Canadian businesses. They also work to promote businesses that are trying to invest in Canada as well, in conjunction often with Foreign Affairs and International Trade Canada.
There are individuals such as Glenn Williamson of the Canada Arizona Business Council. In 2005 the bilateral trade value between Arizona and Canada was set at $2.5 billion. The goal of that organization was to bring that to a total of $5 billion by 2008, and they've succeeded in doing that.
That's one example of how, economically, they've contributed significantly to Canada.
