I wasn’t able to find any information on the photographer and I can’t judge dates based on men’s clothing. I just don’t know them that well.
His photo was taken in Sundridge Ontario by Faulkner. (Sundridge is north of Toronto). I found Faulkner mentioned on this site.
John Crosby Faulkner (25 April 1843 to 16 February 1932) worked in Sundridge between 1889 and 1907, and is also documented there between 1914 and 1920. He operated a photography studio and fancy goods store on Main St.
I think this card is in the 1889-1907 range and not the teens and twenties date.
