For a start, that's the wrong question. As you already know, Canadian and Swiss aren't languages, but rather names for the denizens of Canada and Switzerland. Therein lies the problem. There are 246 Internet domains in the world, each representing a political entity such as Japan, Canada, and Switzerland. From an Internet perspective, the political entity must combine with language and culture to create a distinct market.
Japan is a homogeneous market where everyone speaks Japanese.
Canada is a multicultural country where English and French are the official languages, thus comprising two distinct markets. Provincial variation aside, these two linguistic markets, plus a growing population of Mandarin speakers in Vancouver and Toronto, mean that Canada actually comprises three markets. Three or four markets, depending on the commercial reach of Romansch. In some cases, it may make sense to target only one of the markets within a country, national laws permitting. Then they might move on to countries in Western Europe, where many people speak English and are FedEx-accessible.
