Founded by Europeans, still mostly populated by people of European ancestry, with laws written by Europeans and based on European ideas.
European isn't just a geographic descriptor :-)
You do realise that British implies Scottish don't you? On which island do you think Scotland is located?
Have you been to Canada any time in the past few decades? Around half of the population of Toronto, Canada's largest city, is foreign-born. And I promise you it is not predominantly British or French people.
"In 2021, more than 8.3 million people, or almost one-quarter (23.0%) of the population, were, or had ever been, a landed immigrant or permanent resident in Canada. [...] Just under 6.4 million people born in Canada had at least one foreign-born parent in 2021, representing 17.6% of the total population" [0]
In other words, as of 2021, about 41% of the population were either foreign-born or had at least one foreign-born parent. In large cities where most people live, it is even higher.
And the future does not look any more British or French, either.
"In 2024, more than two in five newborns (42.3%) in Canada had a foreign-born mother (i.e., a mother who was born outside Canada), a proportion that has nearly doubled in just over a quarter of a century (22.5% in 1997)." [1]
"According to Statistics Canada's recent population projections, immigrants could represent from 29.1% to 34.0% of the total population by 2041." [0]
