A Mexican-born construction worker says he hung his native country's flag high above Vancouver to remind Donald Trump that his compatriots built a 63-storey tower that carries the billionaire's name.

Diego Reyna has drawn the attention of international media after hanging a Mexican flag atop the Trump International Hotel and Tower over the weekend and recording a 43-second video that said the building wouldn't exist without immigrants.

In the video he says Mexicans performed everything from drywall to concrete finishing on the project. During his campaign for the Republican presidential nomination, Trump has been criticized after suggesting some Mexicans entering the U.S. are murderers and rapists.

Reyna says said in a separate Facebook post that Mexicans didn't steal or rape but just did the best work they possibly could.
