A trust account benefiting the young son of slain Hamilton reservist Nathan Cirillo has been set up by the family and the Argyll and Sutherland Highlanders of Canada.

The 24-year-old was fatally shot while guarding the National War Memorial in Ottawa this week.

The public can donate by going to any TD Bank branch and asking to give money to the Marcus Cirillo Trust, said Lt.-Col. Rick Kennedy, chair of the Argyll Regimental Foundation.

Almost $190,000 of a hoped-for $200,000 had been raised by early Friday afternoon. A contribution of $100,000 was made by the country's five big banks.

They also have an agreement with the military family support agency True Patriot Love Foundation. Those wishing to donate electronically can go to truepatriotlove.com and earmark funds for Cirillo or to standonguardfund.com

Kennedy said they needed to take time to set up the account carefully.

He cautioned people not to donate to other fundraising accounts advertised online.

At least one online account was referred to the RCMP for investigation.
