BEIJING/OTTAWA—China expanded its ban on Canadian canola seed imports on March 26 to include shipments from Viterra Inc, the latest development in a wider trade dispute between the two countries.

Viterra is the second canola exporter to have its registration canceled, after Beijing halted shipments from top exporter Richardson International earlier this month.
