oh no... you don't need because when my dad went to Turkey he used visa which is from Canada

You need to apply it at Consulate General to obtain tourist visa. The turkish visa is also valid for Northern Cyprus. Note that you are required to have a certain amount of money (50 $ per day) while you enter Turkey.

If you are not leaving the international airport transit area you do not need a transit visa.

However if you plan on exiting the area then you will have to apply for one
