Chaves has been performing stand-up comedy since 1995. She has toured the comedy-club circuits in Canada, the United States and Latin America, and performs in English, Spanish, French and Italian. Chaves first performed at the Just for Laughs gala in 1998 and has been a regular at that Montreal festival and other major comedy festivals including those in
Halifax,
Winnipeg, Edmonton, Vancouver, Boston, and in Bogota, Colombia. Chaves has also performed for the Canadian Armed Forces at
CFS Alert and in Egypt, Israel and Afghanistan, and for the 2012
Nobel Women's Initiative delegation to Central America. She warmed up an audience of 43,000 before the
2015 Pan American Games opening ceremony and hosted the 2016
ACTRA Awards. She has had two nationally televised stand-up comedy specials:
Comics! on CBC and ''There's Something About Martha'' on CTV and The Comedy Network. She frequently performs on CBC Radio's
The Debaters,
Because News and
Laugh Out Loud; she was one of the latter show's five most-requested performers who appeared at their 10th anniversary gala. Chaves performed at a comedy show for the
BBC World Service when it recorded an episode of
The Arts Hour in Montreal. Chaves
came out publicly around 2009 and began working her experience as a homosexual person of colour into her material. At about this time she began writing and performing in a series of one-woman shows. Her semi-autobiographical play
In Times of Trouble, about a lesbian woman returning to Guatemala to care for her dying born-again Christian mother, premiered at the Soulo festival in 2014 and opened the Caminos Pan-American arts festival in 2015. While continuing to perform mainstream shows, Chaves performs many gay, Latin or ethnic events. She headlined in Canada's first LGBTQ+ comedy tour,
Queer and Present Danger, which performed in more than 25 cities. She also headlined in
The Ethnic Rainbow, Canada's first comedy show featuring LGBTQ comedians of colour. Chaves performed in multiple showcases at
Toronto Pride. Chaves was nominated for the
Canadian Comedy Award for Best Female Standup every year from 2001 to 2006. She won the award for Best Standup Comic of 2017. ==Activism==
