The impact of Covid pandemic is inequitable on countries of the world. While some countries have rebounded despite a severe case of pandemic influence, such as the US, some others did not receive as hard a shock of the disease. In this paper, the authors focus on the Covid-19 effects on macroeconomies of the US, Canada and Mexico - three countries that signed the newly adopted Free Trade Agreement after North American Free Trade Agreement (NAFTA). It is seen that the Covid effects are drastically different in these economies, with the US getting the worst of it. Policies adopted were precautionary in Mexico, but quite liberal in the US and Canada. The trade agreement clauses had to be either modified or completely discarded. The immigration problem at the southern border of the US has added more burden on the trade agreement. The paper discusses these aspects.
