Sarah Elmeligi has taken Banff-Kananaskis.
The only rural riding in Alberta that went to the opposition on election night.
The seat was previously held by the UCP's Miranda Rosin.
Rosin won in 2019 with just 51 per cent of the vote.
Elmeligi had 11,487 votes, while Rosin had 11,288, a difference of only 199 votes.
Both Elmeligi and Rosin claimed victory late Monday evening.
The Banff-Kananaskis riding was just created in 2017 when Cochrane moved into a new riding with Airdrie to form Airdrie-Cochrane.
