@dlowan,
Ok...according to Wikipedia:
http://en.wikipedia.org/wiki/Immigration_to_Australia#Country_of_Birth_of_Australian_Residents
According to the Australian Bureau of Statistics[17] in mid-2006 4,956,863 of the Australian resident population were born outside Australia, representing 24% of the total Australian resident population.
24% is a HELL OF A LOT!!!!!!!!

I would say that table only shows larger goups,..because we have a lot of Middle Eastern folk, and Africans, and Chinese and Islander and Maori. I would also say that since 2006, Oz has targeted areas like Sudan and Somalia, and Afghanistan...so the percentage of very different cultures has increased.
Of course, the Brits tend to assimilate really well, so they hardly count.
Remember, we have a much smaller population that the US or Canada, so immigrants have more impact relatively speaking.
Here's what I could find re Canada;
http://en.wikipedia.org/wiki/Immigration_to_Canada
Currently Canada is known as a country with a broad immigration policy which is reflected in Canada's ethnic diversity. According to the 2001 census by Statistics Canada, Canada has 34 ethnic groups with at least one hundred thousand members each, of which 10 have over 1,000,000 people and numerous others represented in smaller amounts. 16.2% of the population belonged to visible minorities: most numerous among these are South Asian (4.0% of the population), Chinese (3.9%), Black (2.5%), and Filipino (1.1%). Outstripping visible minorities in proportion, however, were (non-British or French) invisible minorities, the largest of which were Irish (13.94%), German origin (10.18%), and Italian (4.63%), with 3.87% claiming Ukrainian origin, 3.87% claiming Dutch origin, and 3.15% claiming Polish origin ("North American Indian", a classification which may include in-migrants from indigenous peoples of the United States and Mexico but which for the most part are not considered immigrants, comprise 4.01% of the national population). Other invisible minority ethnic origins include Russian (1.60%), Norwegian (1.38%), Portuguese (1.32%), and Swedish (1.07%).[2]
In 2007, Canada received 236,760 immigrants. The top ten sending countries, by state of origin, were People's Republic of China (28,896), India (28,520), Philippines (19,718), Pakistan (9,808), United States (8,750), United Kingdom (7,324), Iran (7,195), South Korea (5,909), Colombia (5,382), and Sri Lanka (4,068).[3] The top ten source countries were followed closely by France (4,026), and Morocco (4,025), with Romania, Russia, and Algeria. each contributing over 3,500 immigrants.
I can't see a percentage of population, except it's increasing.
US
I can't get a percentage, but I think it's big.
You guys have Hispanics overtaking Anglos in a lot of big cities.
Seems to me you're doing pretty bloody well, given that.
