Since the 1990s, Johnston has been notably forthcoming in her discussion of the abuse inflicted on her by her mother and her first husband, and being unprepared to be a mother to her son Aaron—topics that have also been reflected in the strip. A column by
Jan Wong of
The Globe and Mail, reprinted in
Lunch with Jan Wong, notably portrayed Johnston as somewhat difficult and irascible. Johnston resided in the
Northern Ontario town of
Corbeil for many years during
For Better or For Worses run. Johnston had talked about either ending
For Better or For Worse or handing it off to another cartoonist, but changed her mind as a result of her split from her husband of over 30 years. In September 2015, Johnston and her daughter moved back to
North Vancouver. Johnston had a close friendship with
Charles M. Schulz, creator of
Peanuts. She wrote the introduction to one of the volumes of
Fantagraphics Books' series
The Complete Peanuts. On 13 March 2014,
Library and Archives Canada announced that it had acquired material to add to its Johnston collection, including 3282 drawings, 296 watercolours, 244 photographs, about 3.5 m of textual items, and a few other objects. ==Awards and honours==
