Please ask an expert to answer the question of immigrating to Canada

Your uncle has obtained Canadian citizenship, and your father cannot apply for immigration as a dependent.

But if your father can apply for Canadian skilled immigration, because your uncle is in Canada, he can get extra points.

If your father can immigrate to Canada, and you are a minor (under 22 years old, unmarried, dependent on parents), you can immigrate with him or he can apply for your immigration. You cannot immigrate to Canada if you are an adult.
