Before the 2016 change, the Liberal Party of Canada belonged to people who paid a fee to become members. That is still the case for the national Conservative, New Democrat, and Green parties.
Why is this important?
Elections Canada forbids political parties from accepting money from anyone who isn’t a Canadian citizen or a permanent resident of Canada. As a result, you can’t join the Conservative, New Democratic, or Green parties if you aren’t at least committed to Canada as your permanent home. Those parties charge a membership fee and can’t legally accept money from anyone who isn’t at least a permanent resident.
Not so the Liberal Party of Canada. Anyone can “register” to belong without payment of any fee. The rules set by the Liberal Party’s National Board of Directors permit registration to anyone if they “ordinarily live in Canada.” The important point is that their living in Canada does not need to be permanent. That standard wording has been left out. It’s enough if someone ordinarily resides in Canada, even if only temporarily. This widens eligibility from people who have genuinely immigrated to Canada to include people with no intention of making Canada their home.
By “registering,” people gain all the privileges of membership, including the right to select candidates even if they are supported by the Communist regime. Non-permanent residents are even able to participate in selecting the next Liberal leader under this system. No permanent commitment to Canada is required. Even the Chinese ambassador could “register” to help nominate candidates or to select the next Liberal leader if he signed to say he supported the purposes of the party.
People putting down permanent roots might still be vulnerable to “police station” tactics by agents of hostile foreign powers, but they are more likely to act in the best interests of their adopted country than temporary sojourners.
Why should we think that other hostile authoritarian regimes won’t also try to exploit the same loophole if they can?
Without further investigation we won’t know how many temporary residents helped candidates favoured by Beijing win Liberal nominations. However, even if Canadian security officials had not found existing political interference by the Communist regime, there’s no doubt whatsoever that the Liberal leadership has invited such interference by enticing non-permanent residents, who lack firm commitment to the collective welfare of Canadians, to make the Liberal Party their home. Doing that violates exactly the concern behind the Elections Canada prohibition which forbids parties from accepting money from non-permanent residents—keeping influence out of the hands of people with no permanent stake in Canadians’ welfare.
Canadians who are concerned about this type of loophole opening our elections to foreign interference can ask for a law to forbid all political parties from inviting non-permanent residents to influence party affairs as members in the same way that parties are already forbidden from inviting non-permanent residents to influence their affairs with financial support.
