Tim Hortons is speaking out about a human-rights complaint launched by four temporary Mexican workers against the former owner of two restaurants in Dawson Creek.

The workers are alleging Tony Van Den Bosch called them Mexican idiots, said he owned their lives and regularly asked for their passports.

Tim Hortons spokeswoman Alexandra Cygal say the company learned about the allegations in the complaint on Friday and Van Den Bosch has not been with the chain since July 2012.

She says the company doesn't condone any of the behaviours or allegations made in the complaint.
