Fresh trade data shows deepening US reliance on Canadian goods, even as the president claims the opposite. …According to the US Census Bureau and Bureau of Economic Analysis, the US goods trade deficit with Canada widened to $4.9 billion in March, up sharply from prior months.

Automotive imports rose by $2.6 billion, including a $2.1 billion spike in passenger vehicles, many of which are assembled in Canada. Oil and lumber purchases also increased, contributing to a 14% month-over-month jump in the broader US trade deficit, which hit a new monthly high of $140.5 billion in March. …The US typically runs a services surplus with Canada, and American firms rely heavily on Canadian supply chains in autos, energy, and materials, as the fresh BEA data suggests.
