Most B.C. New Democrats know David Black as the president of MoveUP, the Movement of United Professionals.

Formerly called Canadian Office and Professional Employees Union Local 378, it represents about 12,000 workers in the public and private sector, including those at ICBC and BCAA.

Some New Democrats are also aware that he's the son of former interim B.C. NDP leader Dawn Black, who spent many years in Parliament as the NDP MP for New Westminster.

This David Black should not be mistaken for the other David Black, who owns community newspapers across B.C.

But now, the union leader David Black is known for something else: he's the first person who's initiated a petition to go before Parliament to ban Donald Trump from visiting Canada.

As of this writing, it has more than 1,000 electronic signatures, with 361 coming from B.C.

The petition was sponsored by Burnaby South NDP MP Kennedy Stewart.

Here's what it says:

Petition to the House of Commons in Parliament assembled

Whereas: Canada is a proudly multicultural nation;

Canadians embrace all people regardless of ancestry or religion;

It is illegal in Canada to incite hatred against any identifiable group;

Republican presidential candidate Donald Trump has unfairly called for all Muslims to be banned from entering the United States.
