Catharine Parr Traill (born Strickland; 9 January 1802 – 29 August 1899) was an English-Canadian author and naturalist who wrote about life in Canada, particularly what is now Ontario (then the colony of Upper Canada). In the 1830s, Canada covered an area considerably smaller than today. At the time, most of Upper Canada had not been explored by European settlers. Traill is considered an amateur botanist, because at the time, it was not possible for women to hold professional, paid positions.
