In Canadian elections every member of parliament (house of commons) is chosen in the electoral district in which he runs. Most of them are affiliated with one of the federal parties (some run independently). Hence, I presume that party leaders also run as members of parliament in their own electoral districts.
Hence, can it occur that a party leader is not chosen in his own district? Does that mean that s/he does not play an active role in the Canadian parliament but only through his party members?
I am just wondering because then it means that the party leader cannot take credit for votes or any other actions done throughout the years where the party leader is supposed (maybe?) to set the tone of the party as a whole.
