> what Canadian grain imports have anything to do with glyphosate?
You want wheat (and other grains) to be dry before harvest. Harvesting when wet increases losses due mold growth. Wet stems cause sticking and blocking in the harvest machinery. In many countries it's common to apply a defoliant: You kill or half-kill the foliage of the crop plants, and wait a small number of days, so grains and stems get drier before the harvest.
This use of glyphosate has nothing to do GMOs (there is no GMO wheat in markets anywhere). In a small number of countries, it's forbidden to use chemicals (plant poisons) to force desiccation.
