Is it obligatory to change the name "Canada" to avoid its meaning "disbelief in Allah's blessings" (al-kufr bi ni'mat Allah), and does registering it as "Kinda," "Kindi," or "Kindy" solve the problem, or must it be changed entirely?

"Kind" (كِنْد) in Arabic means "ingratitude for blessings." As for "Kinda" (كِنْدَا), it has no meaning in Arabic dictionaries, and it is unknown if it has an undesirable meaning in other languages. Therefore, it is advisable to change such names to good names with known meanings.
