Due to its unique architectural character in Toronto, Casa Loma has been a popular filming location for movies and television.

It is also a popular venue for wedding ceremonies,[3] and Casa Loma can be rented in the evenings after the museum closes to the public.

Pellatt commissioned architect E. J. Lennox to design Casa Loma, with construction beginning in 1911, starting with the massive stables, potting shed and Hunting Lodge (a.k.a.

As soon as the stable complex was completed, Pellatt sold his summer house in Scarborough (burned down in the 1920s[4] but the Lennox designed groundskeeper's home at 12 Courcelette Road remains[5]) to his son and moved to the Hunting Lodge.

During the depression that followed the war, the City of Toronto increased Casa Loma's property taxes from $600 per year to $1,000 a month, and Pellatt, already experiencing financial difficulties, auctioned off $1.5 million in art and $250,000 in furnishings.

[13] A 2006 advisory committee led by former MPP Ron Kanter, and its subsequent reports, recommended that the city turn the mansion's management over to a new "Casa Loma Trust".

[7] The city's renewed management agreement included a stipulation that KCCL would use the mansion's net revenues to help pay for upgrades; however, the organization used the fund to cover operating shortfalls instead, and there was only $335,000 in the account by 2011, rather than the $1.5-million originally projected.

[7] As a result, in 2011, the city temporarily resumed management of Casa Loma and began welcoming bids from the private sector in its search for a new operator.

[15] In January 2014, the city entered a new long-term lease and operating agreement with Liberty Entertainment Group, led by President and CEO Nick Di Donato, which agreed to spend $7.4 million to continue the mansion's upgrades.

Among other fixtures, the room featured a 10 feet (3.0 m) high Louis XVI style faux-gilt carved light standard with 24 bulbs.

Their first visit was in 1913, when 250 girls and their leaders toured the conservatories and stables, climbed the circular staircase to the top turret and then were served tea in the Palm Room.

In March 1914, Lady Pellatt watched the Guides' annual fête from her bedroom window as she was too ill to leave her room.

[citation needed] As of 2014[update], the garage and carriage room feature an exhibition of vintage cars from the early 1900s.

Comic books and children's novels that have used it include the Scott Pilgrim series and Eric Wilson's murder mystery The Lost Treasure of Casa Loma.

[23] TV show Hemlock Grove was also filmed there as well as The Mortal Instruments: City of Bones and related Shadowhunters.

[25] In 2018, Casa Loma served as a filming location for the 2019 American black comedy thriller Ready or Not.
