The attacks occurred just before the police service kicks off Sexual Assault Awareness Month.
Police say two women were assaulted at separate times while walking along a path in High Park on Sunday evening.
The first incident occurred at about 7 p.m.
A man allegedly approached the woman, obstructed her from walking and then sexually assaulted her.
Police say he man is about 40 years old, bald with an olive complexion and high cheekbones. He is described as having a medium build. He is between five feet eight inches and five feet nine inches tall and was wearing a dark-blue, green or grey hooded sweatshirt.
The second incident occurred at about 9 p.m.
A man allegedly grabbed a woman around her abdomen from behind while she was walking, threw her onto the ground and sexually assaulted her.
Same man may be responsible: police
Police say the man in the second incident is between 40 and 55 years old, has an olive complexion and high cheekbones, and is bald. He is described as being between five feet six inches and five feet nine inches. He was wearing a blueish/grey hooded sweatshirt.
The same man may be responsible for both attacks, police say.
"At this time, I can't say for sure that they are connected. They are very similar in their modus operandi. The composites are very similar," said Insp. Joanna Beaven-Desjardins.
"It appears that the suspect is quite aggressive. He approached both of them and attacked them. It is a very public park; we know that there's a lot of people in there," Beaven-Desjardins said.
Police say they will be handing out composites and anything related to these incidents at High Park this upcoming weekend.
