I don’t know how to be clearer for you.
A hard stance looks like this:
"Canada values its strong partnership with the United States and acknowledges the concerns raised over our proposed DST. In a show of good faith and commitment to reaching a balanced trade agreement, we are suspending the DST indefinitely.
However, if a mutually acceptable agreement cannot be reached, Canada reserves the right to implement the measure as planned. Our goal remains a fair and forward-looking solution that supports a level playing field for all."
Thus we reached trumps goal - DST doesn’t move forward or go through. It stays exactly where it is, but its not a concession for nothing, and makes it clear that the DST remains part of the negotiations.
What proof you have he will? He has given no indication of it, and it is currently canceled.
