In 1892, the Irish-born businessman founded Crown Cork and Seal in Philadelphia to manufacture his latest and greatest invention, which he called the “crown cork.”

This bottle cap factory opened in 1929 and was expanded several times.
Like a number of plants on Carlaw, it was a subsidiary of its American parent company.
Like Wrigley, Crown Cork and Seal moved to a new plant outside the city’s core in the 1960s.
It was north of the city limits on Keele Street, directly beside a massive new Canadian National Railways freight yard and major highway.

The new factory was especially designed to handle a popular new product line – aerosol cans.
Many of the 240 staff at the Carlaw factory followed their job north and the total number of staff employed by the company in Toronto increased to 300.
The Diament Knitting Mill later used this building for several decades.
Still, the area declined economically as factories continued to close into the 1990s.
Living Memory
“[In the mid-1980s] everything closed down at 5 pm … I was afraid to be on the street. It was desolate. Windows were boarded up. There was a lot of vandalism. Landlords were desperate to just cover their costs and were letting the buildings deteriorate.”

co-owner of several Carlaw Avenue
buildings, speaking to the

This building was one of the first in the area to be fitted with live–work units.

In 1996, Gyan Jain, an engineer who migrated from India to Canada in 1964, bought this building and installed hundreds of small, affordable units that were popular with photographers, artists, entrepreneur, and professionals.

Note the “for rent” signs on the building.

In 2008, the Jain family also bought and converted part of the former Rolph-Clark-Stone plant into residential lofts.
Living Memory
“We took a mortgage back from the vendor. He had a toy factory. Half the building was vacant, the other half rented out. When he saw me taking the plywood off and replacing the windows, he said, ‘Mr.Jain, what are you doing? They will just be vandalized again.’ I said, trust me. If I respect my buildings, they will as well.”

Look carefully at your next canned drink. A small crown symbol indicates that it was made by Crown, now one of the continent’s leading packaging companies.
