Don Ferguson said Abbott, 64, died Saturday night at Toronto General Hospital, 14 years after being diagnosed with chronic lymphocytic leukemia.
He kept the progressive disease secret from all but a few close friends and family until a week ago, Ferguson said.
"Roger was the guiding light of Royal Canadian Air Farce since it began in 1973, and all of us who have had the honour of working with him and the pleasure of knowing him will dearly miss his kindness, generosity, integrity, leadership and wonderful sense of humour," he said.

A firefighters holds a hose on the scene of a three story apartment building fire in Woodstock, Ontario, Sunday, March 27, 2011. Seven people were taken to hospital and up to 11 more are unaccounted for, police said.
With a large part of the three-storey building now turned to a pile of smoldering rubble, police said the outlook for those missing was grim.
"If we don't have any fatalities, I'll be very surprised," Sgt. Marvin Massecar of Woodstock police said late in the afternoon.
Raging flames tore through the building after nearby residents reported hearing a thunderous explosion and feeling the ground shudder early Sunday morning. Plumes of black smoke could be seen from the distance as fire crews worked to douse the blaze.
At one point, it looked like much of the building's facade was consumed by roaring orange flames, which caused the structure to crumble into a heap of bricks and twisted metal.
Seven people, including a firefighter, were injured in the blaze, police said. Six of those hurt were treated at Woodstock General Hospital and released. One person remained in hospital with non-life-threatening injuries.
By Sunday evening, police had taped off a large area surrounding the building and evacuated all the homes on Victoria Street.

Surveillance is now a multibillion-dollar global industry, and an increasingly pervasive part of our daily lives.
More than half a century later, it is worth considering how Orwell's fictional prediction weighs up against reality. If Big Brother's gaze dominated that imagined future, who's watching over us now?
In some respects, old George was spot on: surveillance is booming. It's now a multibillion-dollar global industry, and an increasingly pervasive part of our daily lives. But today's version has evolved beyond the Big Brother model - a monstrous oppressor peering down a giant microscope - into a more sophisticated, multi-directional and complex beast. Surveillance has spawned so many offshoots, and spread in such unforeseen directions, that we are struggling to keep up with its ethical and legal ramifications. What's more, in the digital age, we as individuals are not always its helpless victims. Unsettling? Perhaps. But rather than blindly condemning or embracing these shifts, it's better to keep a watchful eye on them.
Boston -- Health officials said Sunday that one sample of Massachusetts rainwater has registered very low concentrations of radiation, most likely from the Japanese nuclear power plant damaged earlier this month by an earthquake and tsunami.
John Auerbach, the Massachusetts commissioner of public health, said that radioiodine-131 found in the sample - one of more than 100 that have been taken around the country - has a short life of only eight days. He said the drinking water supply in the state was unaffected and officials do not expect any health concerns.
Nevada and other Western states also have reported minuscule amounts of radiation, but scientists say those presented no health risks.
The fresh protests took place in the cities of Berlin, Hamburg, Munich and Cologne following the nuclear crisis in Japan triggered by the earthquake and tsunami, a Press TV correspondent in Berlin reported.
German Chancellor Angela Merkel was quick to react to the catastrophe in Japan, announcing a three-month moratorium on extending the lifespan of Germany's nuclear power plants.
Still, demonstrators took to the streets in Germany in large numbers. Placards read slogans like "Fukushima is a warning." A minute's silence was also held to honor Japan's quake and tsunami victims.
"Today similar protests have been held in Munich, Cologne, Hamburg and Berlin. We expected tens of thousands, but the turnout has been higher than our expectations," Thorben Becker, a nuclear expert, told Press TV.
This is the second time the USDA has been sued over its approval of Roundup Ready alfalfa, which is genetically engineered (GE) to tolerate glyphosate, a popular herbicide commonly sold under the Monsanto brand name Roundup. The latest lawsuit, filed by groups like the Center for Food Safety (CFS) and the National Family Farm Coalition, opens a new chapter in the five-year battle over the GE alfalfa seed developed by Monsanto and Forage Genetics.
Industry watchdogs and farmers say that Roundup Ready alfalfa will increase reliance on already overused herbicides like Roundup, encourage the spread of herbicide-resistant "superweeds" and contaminate organic and conventional alfalfa with Monsanto transgenes through cross-pollination.

Philip Caminiti, left, the pastor of Aleitheia Bible Church in Black Earth, Wis., and his brother, John Caminiti, 45, have been charged with a dozen counts of child abuse for allegedly using wooden rods to punish children.
The pastor and seven members of a small church in central Wisconsin have been charged with using wooden rods to spank infants as young as 2 months old for "being emotional, grumpy or crying," the Dane County Sheriff's office said.
The Aleitheia Bible Church, in the town of Black Earth, was started in 2006 with a donation in the range of $500,000-$600,000 from Bob and Lori Wick of nearby Mazomanie, according to a news release from the sheriff's office.
Lori Wick is the author of almost three dozen historical Christian novels with more than five million books in print, according to her Amazon profile. Reached by AOL News today by telephone at their home, Bob Wick said they "have no comment" on the case.
The apology came after employees fled the complex's Unit 2 reactor when a reading showed radiation levels had reached 10 million times higher than normal in the reactor's cooling system. Officials said they were so high that the worker taking the measurements had withdrawn before taking a second reading.
On Sunday night, though, plant operators said that while the water was contaminated with radiation, the extremely high reading was a mistake.
David Kelly inquest plea made to David Cameron
A group of doctors campaigning for a full inquest for Dr David Kelly have appealed to Prime Minister David Cameron to intervene on their behalf.
The doctors have questioned Lord Hutton's 2004 verdict of suicide on the government weapons inspector.
Many of the companies on Saturday avoided Tokyo Bay, which is home to two major ports of Tokyo and Yokohama,The New York Times reported.
Chinese officials had detected radioactive contamination in their cargo ship having sailed at least 80 miles farther from the Fukushima Daiichi nuclear power plant that was damaged by the March 11 earthquake and tsunami.
Although some cargo ships enter ports south of Tokyo, many others have totally cancelled any shipment to Japanese ports until further notice.
