Almost all of the federal political parties have a full slate of candidates, but today is their last chance to make changes.

The Liberals, Conservatives, NDP and Greens will be represented in all 338 ridings across the country.

The People's Party said that as of Sunday it was sitting at 326 candidates, with no nominated candidates in Prince Edward Island.

After 2 p.m. local time today, the candidate nomination process closes.

That means if candidates withdraw or are kicked out, parties won't be allowed to fill their slots.

"That's why we encourage candidates not to wait until the last minute, because if there is a mistake or an error, that would have been past the deadline," Nathalie Demontigny of Elections Canada told CBC News last week.

Candidate vetting in the age of social media has created hiccups across the board during this election season.

Candidate woes

Each of the parties has booted or reviewed candidates, most of them for racist or inappropriate comments and social media posts.

The Liberals turfed well-known imam Hassan Guillet after anti-Semitic comments surfaced. The Conservatives kicked out Cameron Ogilvie over discriminatory social media posts. The NDP booted Dock Currie because of online posts. The Greens have been forced to re-vet candidates after anti-abortion comments came to light, leader Elizabeth May said. And the PPC expelled a candidate after he asked leader Maxime Bernier to denounce racism.

The PPC lost another candidate on Monday. Chad Hudson issued a statement saying he would not be standing for the party in the Nova Scotia riding of West Nova "due to information regarding the People's Party's values and the choices its leadership have made."

Breaking it down

The NDP had a slow start to its nominations process, with several dozen candidates missing as the campaign started. The Conservatives and PPC have had almost a full slate since campaign kickoff day at the beginning of September.

Conservatives say 107 of their candidates are women — a record for the party.

The NDP provided a full demographic breakdown of its candidates. Almost half of its candidates — 49 per cent (166), are female, while 24 per cent (80) are racialized, 12 per cent (40) are from the LGBTQ2 community, 12 per cent (39) are youth candidates, eight per cent (27) are Indigenous and five per cent (17) are living with a disability.

The Green Party said 46 per cent (156) of its candidates are women and four are non-binary; five per cent (18) are racialized, four per cent are (12) Indigenous and eight per cent (28) come from the LGBTQ2 community.

To be eligible to run, a person must be 18 and a Canadian citizen and must have collected the names, addresses and signatures of at least 100 qualified electors.

A candidate can still withdraw his or her nomination by 5 p.m. local time on Sept. 30. But they must personally file a written statement of withdrawal with the returning officer, sign it and have it witnessed by two qualified electors, according to Elections Canada.
