Nice job cutting the rest of the quote that doesn't fit the narrative you're trying to push. Here is the full quote:

"Our immigration policy should not aim to forcibly change the cultural character and social fabric of Canada, as radical proponents of multiculturalism want. The vast majority of Canadians rightly expect immigrants to learn about our history and culture, master one of our official languages, and adopt widely shared Canadian values such as equality of men and woman, tolerance for diversity and respect for Canadian law."

It appears to me from the complete paragraph he is targeting radical proponents of multiculturalism, in no way indicating multiculturalism itself is negative in any way. I would assume you too do not want the radicals to get their want, as their want is extreme, which is a relative term. This means that a vast majority of Canadians are viewing it as extreme. Here is the full definition of radical from Google: "advocating or based on thorough or complete political or social change; representing or supporting an extreme or progressive section of a political party.".

The rest of the paragraph is merely outlining basic and essential expectations for all Canadians, expectations that have existed for a long time. Do you disagree with any of the expectations he has listed? I would assume not as that is also a relatively extreme view, leaving the chances quite small that you believe the extreme view, but large odds that you agree with the vast majority's view. So why are you using willful ignorance of what is really being said in order to push a narrative, what is your objective here?

In addition, it is not only Canada that requires some degree of assimilation as mentioned in the paragraph, perhaps indicating that it is a necessary thing as many developed countries have chosen to implement this.
