Due to donation limits ($1700 / year), it's hard to amount to much unless you sprinkle it across all members of the household and donate to the party and EDA too.

@OminousOrange @mooniyaw You can thank #JeanCretien for getting #Corporate money out of politics (at least, by direct donations). Surprisingly, #StephenHarper reduced personal contributions even further (a way of owning the #Libs as at the time their party was much better at attricting lots of small doners).

In 2019 Canada enacted Bill C-76 which allows third-party donations (somewhat equivalent to America's super PACS) which allows unlimited donations ... from here:

Can I donate to third parties?

Even if you are not organizing events or producing advertising, you may still choose to engage in the election by making contributions to third parties to support their regulated activities. Unlike political contributions, individuals, businesses, and other organizations are permitted to make contributions to third parties, and are not subject to any monetary or non-monetary limit on the amount of their contributions.[30] A third party, however, must not use funds from a foreign entity to pay for regulated activities.[31]

Each contributor’s name and their contribution amounts must be reported in the third party’s financial returns, which are then published on the Elections Canada website.[32]
