Do Canadian woman have to bump up the number of births in Canada?

No.

First, Syrians are Asians.

Second, if you mean Asians as in Chinese, Philipino, or East Indians... these people already speak English. India is a native English speaking country, and China and the Philipeans have massively high rates of English speakers and nearly all must speak English (or French) in order to even apply for permanent residency in Canada. Chinese have massively high rates of education and language skills within Canada.

Third, there is no reason Canada needs any specific population. It could merely allow its low birth rates to decrease its population.

Forth, there is no reason that Canada can't maintain a population via immigration. It has a large population of Chinese, East Indian, and Philippines with almost no serious downsides. It can easily accept more skilled workers, skilled trades workers, investors, etc. and less refugees. It can also increase the number of Europeans (specially UK citizens) if it somehow needed more 'white' people.

Fifth, Asians actually don't have high birth rates. There are almost no countries in the world which have sustainable (2.1 or higher) fertility rates. Only countries which do are sub-Saharan Africa and the middle east. China, Philippians, India, South East Asian, South America, Europe, etc. all have sub 2.1 rates.

Sixth, birth rates are almost universally tied to wealth, education, and women's rights. However, since Canada screens immigrants based on these (skilled workers, skilled trades workers, investors, provincial nominees, etc.) fertility rates are already close to Canadian norms. The highest fertility rates for immigrants (Muslims) only have a 2.4 fertility rate (vs. 1.63). That is barely above replacement to start with. However, those second generation Canadian Muslims are 1.83 -- still below replacement.

I don't know but not everyone wants 2 children. It's beautiful to have children but it's also a lot of work

No. I don't believe they have to.

Only black women are doing this. We should not let blacks come into the country and turn it into a ghetto.

Okay, go find a partner and make babies.
