These are big changes.
First, children born to Canadian citizens may no longer automatically receive Canadian citizenship, even when both parents are. If you're having a kid here, check with the consulate on the new rules or you may have to apply for citizenship for your sprog.

If you married a Taiwanese and were forced to give it up by the Taiwan government, getting it back may be possible just by applying. Again, check with the Canadian consulate for legal specifics.
