All the posts I'm reading are "Canada has no culture". Seriously?
Of course Canada has a culture; Quebec has a more unique example, but for English Canada there are a lot of cultural similarities between their culture and the United States' culture, so most of those characteristics are subsumed under the US cultural umbrella. Canada's resulting perceived culture is more fragmented, less in your face than other cultures. We could easily lose these fragments and become more 'international' (though most English speaking Canadians get information from english speaking countries, so that means the US and UK mostly). All nationalist cultures will face this in the coming years.
The question, really, is does this constitute a problem? It's a question of identity: 'what cultural groups do you identify with?'. Nationalism has a very real hold on our identity. We need that feeling of belonging to something, and everybody is born into a nation. However, online experience has already show us that 'virtual reality' provides that feeling of belonging and the groups with which we identify and to which we belong have changed drastically. This is a fragmentation of previous groups, and of course the previously established cultural groups are going to fight back.
Of course, the results of this fragmentation remain to be seen. Maybe it's better to belong to a group that all your neighbours belong to so that we share something in common with them, and some weak nationalism has a greater value then we currently understand. Maybe the explosion of smaller groups will allow a stronger connection within the group while a weaker without. I personally think that both are useful, and that Canadians should want to understand their culture, just as all other nations should want to understand their own culture. Having to legislate it in fear of losing it shows mistrust on one side and disinterest on the other, an ugly combination.
