That is an Elections Canada link and it enumerates the 23 parties that ran in this election. The Bridge Party (note that their official title is 'The Bridge Party of Canada') ran only one candidate, so Rap's hope was doomed from the get-go.

From Macleans Magazine here is the party-list and the number of candidates they ran this election:

Number of party candidates
Alliance of the North: 1

Animal Alliance Environment Voters Party of Canada: 8

Bloc Quebecois: 78

Canada Party: 1

Canadian Action Party: 3

Christian Heritage Party of Canada: 30

Green Party of Canada: 336

Independent: 74

Liberal Party of Canada: 338

Libertarian Party of Canada: 72

Marijuana Party: 8

Marxist-Leninist Party of Canada: 70

New Democratic Party: 338

No Affiliation: 6

Pirate Party of Canada: 5

Progressive Canadian Party: 8

Rhinoceros Party: 27

Seniors Party of Canada: 1

The Bridge Party of Canada: 1

United Party of Canada: 1

That is the most current info I could conveniently locate. I think the Greens ran a full slate (meaning one candidate in each riding, so their number on that list should (I think) read 338. However, I was wrong once before in 1967, so please excuse me if I have screwed up.
