IIRC only individuals can donate federally - organizations might be able to donate, but if they can, the limit is a free thousand bucks.

Companies do work around the limits by getting people to donate (line xEO's families), but those are typically in the tens of thousands, not millions.

The Conservatives recorded 211,000 donors, with an average contribution of around $198. The Liberals received donations from more than 118,000 people who gave $128 on average and the NDP saw almost 60,000 donors chip in an average of $105 each.
