MPs elected with less than 1/3 of the vote

I am going back to 1984 and over those eight elections I found 30 instances where someone was elected MP with less than 1/3 of the vote.  For someone to be elected with less than 1/3 of the vote it takes at least four candidates winning a reasonable portion of the vote.   For someone to win with less than 30% of the vote, which has happened four times in the last nine elections, it takes four decent strength candidates

1. 26.75% Brad Trost Conservative Saskatoon Humboldt 2004 (sitting MP Jim Pankiw ran as an independent)

Two people are on the list twice -
Hedy Fry in Vancouver Centre in her first election in 1993 and in her latest in 2011.
Paul Forseth in New Westminster-Burnaby in 1993 and then in New Westminster Coquitlam in 2004

In 1993 all 12 people elected with less than a 1/3 of the vote were in Western Canada.  

Listing them by years

The winning party in the election has win 9 of the close races, the opposition 22.

I am surprised not to see more results from Quebec under the 1/3 mark.   It seems that in Quebec the races are almost always two party even when the province elects MPs from four different political parties.
