Why does Canada insist that any US trade deal must protect its auto sector, according to Ambassador Wiseman?

Ambassador Mark Wiseman stated that 'the preservation of a robust assembly and parts industry in Canada is critical' because it 'makes up a huge part of our industrial complex, both in Ontario and Quebec,' and that 'we need to have those capabilities in Canada. We need to have those jobs in Canada.' He emphasized that Canada cannot accept a trade deal unless it ensures the survival of this sector.

What triggered the new round of US–Canada tariffs, and what are their key features?

President Donald Trump ordered 50% tariffs on $20 billion in Canadian goods after trade talks collapsed, with unresolved issues including tariff relief for medium- and heavy-duty vehicles; Canada responded with $20 billion in retaliatory tariffs set to take effect on September 8, targeting sectors such as wine, furniture, dairy, cement, clothing, fishing rods, and hockey equipment — and notably, these duties apply even to products covered by the three-nation trade deal (with Mexico), which had previously shielded most Canadian exports to the U.S.
