Does a Canadian permanent resident need visa to enter Dominican Republic?

It is called a tourist and may be purchased by filling a simple form and making a USD $10 cash payment upon arrival at DR's airports.

However, if you are in transit staying for less than 24 hours and staying at the International transit area, you might not need it at your own discretion: most foreign-passport holders are allowed to stay for up to 24 hours in the international transit areas of the Dominican Republic.
