Twin Cities grocery store founder Jim Kowalski has died while on a fishing trip to Ontario, according to a relative.
Family member and company employee Deb Kowalski says Jim Kowalski was on a float plane with a friend when he died Thursday.
She says there was no crash, and the friend was not hurt. An autopsy was planned.
Jim Kowalski founded Kowalski's Markets in 1983. He and his wife, Mary Anne, are co-owners of what is now nine stores that employ nearly 1,200 people.
