You have all recommended getting rid of the safe third country agreement, yet if even a small fraction of a percentage of the 11.3 million to 22.1 million people came to a regular border crossing in Canada feeling they could claim asylum and not be immediately turned back, that would cause a fair amount of hardship and overwhelm our system, which is already quite strained, but which does deal with the irregular migrants in a responsible way.
In the case of Ecuadorians, even if a small number of them come next year, when their ability to stay in the U.S. expires.... A new arrangement is necessary. Simply eliminating the safe third country agreement unilaterally would potentially throw our system into chaos.
