Canadian Jews are facing a shortage of Manischewitz kosher wine due to trade tensions and provincial bans on US alcohol imports. The bans are affecting Passover preparations and have led to a surge in the 'Buy Canadian' movement. While some Canadian kosher producers see this as an opportunity to expand their business, consumers are struggling to find alternatives to Manischewitz wine, which is a staple for religious celebrations. The missing wine highlights the impact of President Donald Trump's tariff actions and annexation threats on Canadian consumers and US beverage companies.
