the biggest crime group operating in ottawa now is the HA.
founded in dec 2000 dissolved sept 2016 and re chartered in jan 2018 the nomads chapter.
first pres was former rock machine founder/leader paul porter aka sasquatch.
6'6 400 lbs of pure muscle and gut he controlled chapter on the street until 2011 imprisonment on minor drug charges. prior to his release porter gave up the biker life "allegedly". however this is an often used tactic by bikers to get early release and try to fool l.e. porter has long been a close associate of salvatore cazzetta and the 2 of them founded the rock machine mc. both have since patched over to HA obviously.
i am not sure of porters continued involvement in the cities crime scene as he has not been arrested in past 10 yrs or even mentioned in the media or other investigations as having any influence at all. however w/ the lifelong connection to cazzetta who himself is close to the mafia and has heavy influence amongst quebec HA it is easy to see a possible role for porter as the link for drugs moving into the ottawa area.
that being said ottawa is not a city where drugs arrive directly. there are very few cases of drugs of any kind moving directly from source country to ottawa. the cities drugs come from mtl or toronto depending on what crime group is dealing the weight. the HA are the only crime group that have the ability to do that in the ottawa area.
HA have in the past moved away from downtown street level drug dealing and "rent" the space or collect a tax from street gang dealers or independent dealers for the right to operate. HA deal in multi kg level cocaine dealing,pot grow ops,money lending and a litany of other crimes as most HA across canada do.
since the re opening of the chapter in 2018 things have been quiet in the city and surrounding country side w/ small arrests here and there. patrick lock was a name mentioned as a possible new leader of chapter. lock has a long history w/ HA and was purported to have been named by the powers that be in QC HA as leader.
the most recent HA news from 2020 was the murder of a soon to be full patch greg slewidge in carleton place which is about 30 min from downtown heading south. slewidge was found at his residence murdered and as usual....no info from police or media. his father used to sing national anthem before the ottawa senators hockey games and was a former opp officer. there is no evidence that his father being a former cop had anything to do w/ murder as it was common knowledge in the area.

the HA have a puppet club the red devils which operate across the city and into gatineau qc.

the only other biker mc of note is the outlaws mc chapter.
this chapter has been in ottawa since the 70's and has remained fairly quiet over the years as well as its puppet club the black pistons mc.
used to see some black pistons roaring around but not in a little while now.
i will also say that when there is a drug bust the media and l.e. like to state that there was biker paraphenalia found during the search or bust but do not say from which biker mc. vey frustrating and sometimes they don't reveal the club name for months or even years making it hard to decipher who is getting pinched.
to my knowledge the outlaws to not control much in ottawa but the chapter is still open.
