Silveira was born in Canada to Portuguese parents and lived in Mississauga and attended local Catholic schools. He considers himself Portuguese-Canadian and he lived in Portugal for 6 years in his youth and he speaks fluent Portuguese. When he was a child, he knew he was a boy and asked his mother to buy him a penis like his brothers. Growing up, he identified as a lesbian. In 2004, he came out to himself, family, and friends as a transgender man. In an interview published in The Advocate, Silveira states that he feels "transgender by definition, but not by identity", because being transgender has become a political identity rather than a personal one. In 2010 he began hormone replacement therapy.

While the lineup changed over the years, The Cliks have released four albums and with one of their songs appearing on the and toured with Cyndi Lauper on the True Colours Tour.

Silveira was the first openly transgender man signed to a major label in 2006, at the age of 33. Before coming out as transgender, Silveira composed and performed folk music. After coming out, however, he shifted his focus to rock music. Describing his shift from folk to rock music, Silveira says, "When I finally came out as being trans, I found myself freer to explore that darker, more hard-core side, and my songwriting started getting heavier and heavier." In 2007, The Toronto Star suggested that Silveira was about to become "the first transgendered pop heartthrob ever to register on mainstream radar”. He was also voted as the "sexiest Canadian man" in Chart Attack's 15th Annual Readers' Poll making him the first trans man to win the award.

Starting with Wham!'s song "Freedom" and also covered artists like Robyn, Kanye West, Lady Gaga and Justin Timberlake. When asked why he started this project, he explained that he did it for the sake of "doing a cover every like couple of weeks”. When his hormone replacement therapy began in 2010, viewers both began asking for recordings of the covers as well as asking questions about his changing voice. Silveira has not only been described as a role model for other transgender singers, but his covers on Youtube “enabled listening practices that reimagine engagement with contemporary musical archives and the temporality of trans experience.” However, upon reflecting on this early success with a major label, he was shocked that "the band quickly hit a glass ceiling" where the "main focus wasn’t on my music. It was very much on my gender identity."
