What are the requirements for dual citizenship in Philippines and Canada?

In the Philippines, Dual Citizenship is allowed under the Dual Citizenship Law (Republic Act No. 9225) for those who were natural-born citizens but lost their citizenship upon acquiring a foreign citizenship. They must apply for retention or re-acquisition of Philippine citizenship, typically through a petition to the Bureau of Immigration.

In Canada, dual citizenship is permitted, and there are no specific requirements to maintain it. Canadian citizens can hold citizenship in Another Country without losing their Canadian citizenship, but they must adhere to the laws and requirements of both countries.
