Trans Trudeau aide defends running female race and beating girl aged TWELVE to the fastest time

A transgender aide to Justin Trudeau's minister for women has defended her participation in a race where she beat a 12 year-old girl to the 'fastest female' title.  

Nathanielle Morin won a women’s 5km road run by almost six minutes in Ottawa, Ontario in February 2024, demolishing the rest of her competition in the 30-39 year-old female category with a finish time of 25 minutes and 32 seconds. 

The second fastest runner across all women's tournaments that day was 12 year-old Saoirse Hoogenraad with a time of 26 minutes and eight seconds, who ran in a separate age group to Morin. 

But the runner-up in Morin's age category, Maude Bisson, finished a full five minutes 44 seconds behind Morin, in 31 minutes 16 seconds.
