Two women were detained and questioned by a Border Patrol agent because they were speaking Spanish in a store in Montana. The most disturbing part is that the agent said that they don't question people for speaking French even though Canadians are the most likely to cross the northern border illegally. https://www.npr.org/2019/02/15/695184555/americans-who-were-detained-after-speaking-spanish-in-montana-sue-u-s-border-pat
To detain someone solely for speaking Spanish is ridiculous. To do so solely for speaking French would be equally so. Last I heard, people were crossing that Northern border the OTHER way - looking to get into Canada - out of Trump's U.S. Of course, if Andrew Scheer (who believes the world is 6,000 years old) and his Conservatives win the next election --- there could indeed be an exodus.
