Michael Dollard Plante (born 6 January 1967) was a police informer within the Hells Angels East End Vancouver chapter. His story was chronicled in the best-selling 2011 book Hell To Pay by the journalist Neal Hall.

Plante was born in North Vancouver, the son of a teacher. He grew up in Vancouver, Revelstoke, Powell River, Chilliwack, New Westminster, and Burnaby. He graduated from Cariboo Hill secondary school in Burnaby in 1986. In 1990–1991, he studied criminology at Douglas College. He often applied to the Vancouver Police Department, but was always turned down. Plante claims to have been inspired into becoming an informer within the ranks of the Hells Angels by reading the 1996 book Into the Abyss by Yves Lavigne, which is a biography of Anthony Tait.

Plante lived in the Lower Mainland of British Columbia, where he worked as a bouncer while engaging in bodybuilding. Plante worked part-time as a competitive bodybuilder and could bench-press 400 pounds. Plante had no criminal record, but had once been charged with assault. He worked at the bar at the North Burnaby Inn in Burnaby owned by the Hells Angel Robert "Bob" Green. Alarmed at the way that the bar was a front for organized crime, Plante moved to Medicine Hat, but returned to the Lower Mainland when he found things were no different in Alberta with the bars there being used by the Hells Angels. Initially, he worked in a warehouse for Costco, but returned to working in bars for financial reasons owing to the high cost of living in the Lower Mainland. He worked in a series of bars such as the Dell Hotel, the Marble Arch, and the Cecil Hotel which all used by the Hells Angels for their criminal activities. At the Cecil Hotel owned by the Hells Angel Randy Potts, Plante worked as a "mule" smuggling cocaine and cash for the Hells Angels.

Plante had ties with the East End Vancouver chapter of the Hells Angels, which was the most powerful Hells Angels chapter in western Canada. The East End chapter, which was founded in 1983, is considered to be one of the richest Hells Angels chapters in the entire world, and prior to Plante agreeing to work as an informer, police operations against the East End chapter had consistently failed. In the 1980s-1990s, 60% of all criminal cases against the Hells Angels of the East End chapter had ended with the acquittal of the accused. The Royal Canadian Mounted Police officer Bob Paulson told the journalists William Marsden and Julian Sher: "The East End chapter is the most senior, the most powerful. If we were successful in taking them out, that's where we would have the most impact on their operations". The president of the East End chapter was John Bryce who along with his half-brother, the chapter sergeant-at-arms Lloyd "Louie" Robinson (the two men have the same mother, but different fathers) dominated the chapter. Bryce owned a $600, 000 house in Burnaby plus three more houses with a total value of $2 million in the Lower Mainland. Robinson had no job or known source of income, but lived in a condo worth $1 million in West Vancouver. Through Potts, Plante came to know Robinson and served as his "spotter" at the gym where the two men worked out. Robinson recruited Plante to work as an "enforcer" for the Hells Angels whose task to threaten or beat up people along with the promise that he might eventually be permitted to join the Hells Angels. In a sign of favor, Plante in 2002 was first permitted to visit the clubhouse of the East End chapter. In late 2002, Plante first met Bryce and another Hells Angel leader, Gino Zumpano.

Potts was a "prospect" (the second level in an outlaw biker club) and in November 2002, he was beaten up by his enemy Audey Hanson. Most damaging for Potts, Hanson stole his bikers vest with the Hells Angel half-patch. Potts brought along Plante for moral support when met his sponsor, the "full patch" Hells Angel Lloyd "Louie" Robinsonn, to explain that his bikers vest had been stolen. Furious, Robinson slapped Potts across the face and beat him up. Robinson told Potts that he would have to get his Hells Angels vest back or be expelled from the Hells Angels. Potts recruited Plante into a scheme to retrieve the stolen vest and the two men took to watching Hanson's house. In January 2003, Potts gave Plante an Uzi submachine gun and a .38 handgun. Potts told Plante that he wanted him to kill Hanson, not just get back the stolen vest. Plante later commented that having him murder Hanson would limit if not eliminate altogether the legal liability for Potts. Plante and Potts broke into Hanson's house to get back the vest, but Plante intentionally missed when he opened fire on Hanson. Potts was angry that Plante had failed to kill Hanson and told him that he expected him to try again.

Appalled at the prospect of becoming a murderer, especially since the issue at stake was merely a leather bikers vest, Plante contacted the Royal Canadian Mounted Police (RCMP) and stated he wanted to become an informer. In May 2003, Plante was ordered by Robinson to look after his son, Lloyd "Lloydsie" Robinson Jr, who was living on bail after being charged with assault. Robinson ordered Plante to drive his son out to Penticton in the Okanagan valley to hide him, but Plante called the Crime Stoppers phone line along the way to tell the police where the younger Robinson was hiding. Plante stated that he had been ordered by another Hells Angels, David Patrick O'Hara, to bring a businessman, James Betnar, to O'Hara's Surrey home where Betnar was beaten for 15 minutes. According to Plante, O'Hara then told him: "Take him back to Vancouver and get $20,000 from him." After his release from the Surrey Pretrial Center where he had held on charges of extortion and assault in July 2003, Plante contacted the Mountie Douglas Collins about becoming an informer. Plante told Collins: "I am on the verge of becoming a Hells Angel. I work out with Louie Robinson. You have got my wallet. You have seen that I have a club card with all the contacts on it for East End. I am offering you something better – full infiltration."

Plante worked for the RCMP for an operation codenamed E-Pandora. The intention behind Operation E-Pandora was to gather enough evidence to expose the Hells Angels as a criminal syndicate that merely posed as a motorcycle club. Starting in July 2003, Plante met with his police handlers in a van near his apartment in New Westminster. Plante later told Kim Bolan, the crime correspondent of the Vancouver Sun newspaper: "“There was really nothing going on. Everything is pretty quiet. I am actually meeting more with the cops than I am with the Hells Angels." Lloyd "Louis" Robinson, the sergeant-at-arms of the East End chapter was angry with Plante for being arrested and for abandoning Robinson's son in Penticton. As such Plante was out of favor with the Hells Angels in the summer of 2003.

In September 2003, Plante came into Robinson's favor and he finally had information for his police handlers. Plante was sent to Montreal to threaten a witness against Robinson's son into changing his testimony. Upon his return to the Lower Mainland, Plante told Potts about a barrel of ephedrine he had access to, which could be used to make methamphetamine. Plante purchased the ephedrine from the drug dealer Wissam "Sam" Ayach and delivered it to Potts. Plante stated: "I was driving out to this place and I was dropping off first one kilo, then two kilos and then it would take maybe a day or two days to pay me. I did this non-stop from September ’03 till probably December ’03 — just from that barrel." Plante would make deliveries to Pott's mother, who lived in a trailer park in Surrey. Plante recalled: "“I would drop meth off to his mom and his mom would take the meth and she would hand me $25,000. She would say, ‘Is it all there is Michael?’ ‘Yes, Mrs. Potts, it is all there.’ She would say, ‘Do you want an apple?’ ‘No thank you.’". In the fall of 2003 Plante met in a motel room with the Mountie Bob Paulson about signing the contract to become an agent source informer. Plante described Paulson as a man who dressed colorfully wearing a leather coat and cowboy boots.
