Ms Didulo emigrated from the Philippines to Canada as a teenager. She set up several businesses before forming a fringe political party in 2020.
Following endorsements from QAnon leaders, she built up a band of followers, declared that she had overthrown the legitimate government of Canada, and said her claim to the "Queen of Canada" title is backed by secret, powerful US military interests.
On her most popular Telegram channel she has issued "decrees" to absolve her more than 36,000 followers from bills and debts.
That has resulted in followers losing their homes, cars and possessions, according to Christine Sarteschi, a professor at Chatham University in Pittsburgh and an expert on extremism and the sovereign citizen movement - a broad collection of anti-government groups who evade taxes and make up their own fake legal systems.
Ms Didulo and her followers spread a variety of different beliefs, including sovereign citizen, anti-vaccination conspiracies, and ideas related to QAnon - a wide-ranging, completely unfounded theory that says former US President Donald Trump is waging a secret war against elite Satan-worshipping paedophiles in government, business and the media.
While QAnon's spurious narratives revolve around US figures, the theory has taken hold in some parts of Canada and the rest of the world.
