One other thing that I just thought of: we don’t have the perpetual election campaigning that seems to be a feature of US politics. That probably helps drive the partisanship, because it’s so omnipresent, especially with respect to the presidential election.
One reason for the perpetual campaign in the US is that presidential aspirants need to get the nominations, so every four years you have a national campaign starting a year before the presidential election, as is happening right now, with the first GOP debates in August, more than a year before the actual presidential election.
That doesn’t happen in our system. Since we have a parliamentary system, each party needs a leader all the time, not just in the run-up to the general election. The leaders of the parties are chosen well in advance of the next election, and by the members of the party. There is no general public campaign for leadership, but instead a campaign focussed on the party membership. Once elected leader by the party, the leaders tend to hang on for more than one election (except the current incarnation of the Conservative Party federally, which devours each unsuccessful leader after an election).
Here’s the leaders of the five current parties in the House of Commons, and their start dates:
| Leader |
Party |
Leader since |
General elections as leader |
| Trudeau |
Liberal |
2013 |
3 |
| Poilievre |
Conservative |
2022 |

| Singh |

| Blanchet |
Bloc Québécois |
2019 |
2 |
| May |
Green Party |
2006 to 2019; 2022 |
4 |
Our next election is scheduled for 2026. Barring any resignations from any of the leaders, this will be the line-up. (There have been rumours that Trudeau might step down, but I’ve not seen any sign of it.)
At the House of Commons level, there’s a similar dynamic. Since each Commons normally lasts four years, MPs don’t have to be campaigning all the time, unlike members of the House of Representatives, with their two-year terms. It’s also very rare for an incumbent MP to face a nomination challenge from within their party. It does happen, but it’s rare. And, when it does happen, it’s only within the party, not an open public primary.
