[5] Celebrities impersonated by Rosato on SCTV include: Lou Costello (whom he also impersonated when he was a cast member on Saturday Night Live), William Conrad, Danny Thomas, Woodstock co-organizer Chip Monck, SNL cast member John Belushi, Tony Orlando, Don Ho, and Ella Fitzgerald.

[citation needed] Rosato next appeared on the Canadian police drama Night Heat, playing Arthur "Whitey" Morelli,[7] from 1985 through 1989.

[citation needed] Rosato also provided voices for many other animated series including Pelswick, George and Martha, The Busy World of Richard Scarry, The Adventures of Sam and Max: Freelance Police, Mythic Warriors: Guardians of the Legend, Monster by Mistake, The Ripping Friends, Bakugan: Mechtanium Surge, Da Boom Crew, Get Ed and Odd Job Jack.

[1] On 5 May 2005, Rosato was arrested and charged with criminal harassment of his wife Leah, who asserted that his deteriorating mental health had caused her to fear for her safety and that of the couple's infant daughter.

In spite of the diagnosis, Rosato, who denied mental illness and refused to plead insanity, was held for over two years without bail at a maximum-security detention centre.

Brodsky, who called his client's two-year detention awaiting trial "shocking," asserted that Rosato "spent more time in custody on a harassment charge" than anyone ever convicted of the offence in Canada, estimating that "on average, someone convicted of criminal harassment spends one day in jail and two years on probation."

[12] Also, a re-animated version of the Super Mario World episode "Mama Luigi", commissioned and directed by animation artist Andrew Dickman within a year with over 227 animators and artists participating, was dedicated to Rosato and his coworker Harvey Atkin (King Koopa), who had also died later in July that year.
