Individuals of any nationality are normally welcome to apply for funding. What matters is the nationality of your employer, not your own personal nationality.
For example, you cannot be the Principal Investigator on a project if you are a citizen of the Philippines, but an employee of a Canadian university. This is because a university in Canada is not eligible to be the Lead Organisation for the project.
But if you are a Canadian citizen working for a university in the Philippines, you are eligible to apply for funding.
