Gursimran Kaur, 19, was found dead at a branch in Halifax, Nova Scotia, on 19 October.

A GoFundMe appeal to support her family said Ms Kaur's mother, who also worked at the store, had tried to find her after being unable to get through on the phone.

It said other staff had presumed she was helping a customer but that her mother found her "charred remains" a few hours later inside the oven.

"Imagine the horror that her mother experienced when she opened the oven," said the fundraising page, organised by a local Sikh society.

Halifax Police confirmed a 19-year-old had been found inside a "large walk-in oven belonging to the store's bakery department".

It called it a complex investigation, adding: "It is important to note that the investigation has not yet reached a point where the cause and manner of death have been confirmed."

More than C$192,000 (£106,000) has been raised for the family so far, far more than the C$50,000 target.

The GoFundMe page said Ms Kaur was a "young beautiful girl who came to Canada with big dreams".

It said the money would help her father and brother travel from India and the rest would "directly benefit the bereaved family".

The store was closed after the death and a Walmart spokesperson said: "We are heartbroken and our deepest thoughts are with our associate and their family.

"Our focus remains on taking care of our associates and making sure they have the support they need."
