The Toronto Police Service launched the biggest missing-person investigation in their history, forming a 20-member task force and investing more than 25,000 man-hours following up leads.

While it is now considered a cold case, Toronto police and missing-child organizations continue to keep it in the public eye in an effort to garner fresh leads.

They have produced several video re-enactments of Morin's last known movements and released age-enhanced photographs coinciding with anniversaries of her disappearance.

[2] She left the apartment at about 11 am wearing a peach-coloured, one-piece bathing suit, green hairband, and red canvas shoes; she carried a plastic bag containing a white T-shirt, green and white shorts, suntan lotion, hairbrush, a peach-coloured blanket and a purple beach towel.

[4] The first day, police set up roadblocks around the building and circulated vehicles with public address systems to alert neighbourhood residents to the missing child's description.

[8][10] A neighbour recalled seeing an unidentified blonde woman with a notebook on the floor that Nicole's apartment was located on, about 45 minutes before the disappearance.

This organization posted a $1,000 reward, printed posters, and produced a video re-enactment of Morin's last known movements which aired on television several weeks later.

Using biometrical analysis, the researchers claimed a strong resemblance between Morin and a child in a pedophile network in Zandvoort.

[20] Child Find Ontario has also endeavoured to maintain public awareness of the case by arranging for Morin's picture, physical description, and age-enhanced photographs to appear "on electronic screens in Esso gas stations, billing envelopes from Rogers Cable and the Canadian Imperial Bank of Commerce, Toronto Transit Commission display screens, and on the back of transport trucks".

[26] For the 29th anniversary of the disappearance in 2014, the Toronto Police Video Unit produced a re-enactment which was also screened at Mac's Convenience Stores throughout the province of Ontario.

In addition to raising awareness of the case, the run collected $3,000 in donations for the Canadian Centre for Child Protection, which operates a missing-child website.

[27] In 2019, on the 34th anniversary of the disappearance, the Toronto police's missing-persons unit released an age-enhanced picture of Morin suggesting what she might look like in her early 40s.
