At the time, when I asked the license couldn't be certified at the consulate in Puerto Plata and for one reason or another they weren't able to send it to SD in their daily document run.
What they can't do in POP is the step required at the Ministry of Foreign Affairs. Canada not having signed the Hague convention, Canadians must visit the Ministry of Foreign Affairs of the Dominican Republic to stamp the certification issued by the Canadian Embassy (or consulate) and pay the required small fee.
