Two people are facing a total of 141 charges after an investigation into alleged fraud and identity theft in Hamilton.
Police say they began investigating the matter in July 2018, but they have not said what triggered the probe.
They say they searched a home in the east end of the city twice over the course of the probe, recovering bank cards and other forms of identification both times.
A 34-year-old woman is facing 71 charges and a 31-year-old man is facing 70.
The counts include fraud over $5,000, identity theft and possession of property obtained by crime.
Police allege there have been at least 100 victims of the operation to date, but the investigation remains active and anyone with information is encouraged to come forward.

Canada’s prison ombudsman says disturbing and entrenched imbalances mean the proportion of Indigenous people in federal custody has hit a record high of more than 30 per cent.
Correctional investigator Ivan Zinger says the numbers are even more troubling for Indigenous women, who account for 42 per cent of the female prison population.
In a statement today, Zinger says the correctional system seems unresponsive to the needs, histories and social realities behind high rates of Indigenous offending.
He says no government of any stripe has managed to reverse the trend of Indigenous overrepresentation in Canadian jails and prisons despite many inquiries, judicial interventions, and political promises and commitments.
The Correctional Service of Canada says decisions with respect to sentencing are beyond the prison service’s control.
The service does, however, try to influence the time Indigenous offenders spend in custody by providing culturally responsive programs and other efforts aimed at rehabilitation and successful return to society.

A collective of First Nations who support the liquefied natural gas industry in British Columbia say human rights advocates failed to do their research when they called for a pipeline project to be halted.
The First Nations LNG Alliance has issued open letters to the B.C. human rights commissioner and the United Nations Committee to End Racial Discrimination over statements they made about the Coastal GasLink project.
They called for the project to be stopped in the face of opposition from Wet’suwet’en hereditary clan chiefs who say the project has no authority without their consent.
Both said the free, prior and informed consent of all affected Indigenous groups should be granted before any project is allowed to proceed.
Coastal GasLink has signed agreements with 20 elected First Nation councils along the pipeline’s 670-kilometre path but the Wet’suwet’en chiefs say within their territory, those councils only administer small reserves and it’s the hereditary chiefs who hold jurisdiction over a broader area covering 22,000 square kilometres.
Karen Ogen-Toews, CEO of the First Nations Alliance, says in the letter to commissioner Kasari Govender that the pipeline was approved through a democratic process that Indigenous people participated in freely, and neither the committee nor commissioner consulted supportive Indigenous groups before taking a position.

Teenage Indigenous water activist Autumn Peltier says she doesn’t feel the country’s federal politicians are focused enough on climate change.
The 15-year old from Wiikwemkoong First Nation on Manitoulin Island in northern Ontario shared her dismay at their inaction at the World Economic Forum in Davos, Switzerland today.
Peltier was appearing alongside other child activists including Greta Thunberg of Sweden when she made the remarks.
Peltier says she has noticed that politicians are more focused on money and should instead be thinking about the impact and challenges facing the environment.
She says she is finding it hard to capture their attention and she personally does not feel heard by most of them.
Peltier has spent her last eight years advocating for clean drinking water in Indigenous communities and around the world and is the chief water commissioner for the Anishinabek Nation, a political advocacy group for 40 First Nations across Ontario.
