Court documents show the 43-year old Lillooet, B.C., man has a lengthy criminal record and has been convicted of impaired driving at least three times, most recently in October 2014.
The licence suspension from that conviction was still in effect at the time of the crash.
Police have said they suspect the driver in the crash was impaired. CBC News is not naming him because he has not been charged.
The crash killed cyclists Ross Chafe, 50, and Kelly Blunden, 53, as well as the vehicle's passenger, 52-year old Paul Pierre Jr.
The cyclists were riding down a steep, winding hill on the Duffy Lake Road section of Highway 99 when the driver allegedly crossed the centre line and hit them head-on.

The driver was also seriously injured in Sunday's crash and airlifted to hospital in Vancouver accompanied by police.
CBC News attempted to speak to several family members of the driver on Tuesday. None agreed to an interview, but one did tell reporter Megan Batchelor he was still in hospital in Vancouver and now able to walk.
Police are still investigating and have said charges of impaired driving causing death are being considered against the driver.
