The term you want is lenticular printing. Using that phrase should give much better search results than searching for “developing” lenticular images.

If you only need one or a few pieces, try searching for “no minimum lenticular printing” or “short-run lenticular printing.” Some providers specifically advertise small quantities rather than large commercial orders.

So the practical answer is: look for a lenticular printing service/lab, not a standard photo lab, and use search terms focused on short runs or no minimums. If Canada is important, include Canada in the search or check whether the company ships there.
