Jennifer MacIntyre, Canada's climate change ambassador, is stepping down after the sudden death of her husband.
"It is with mixed emotions that I must step down as Canada's Ambassador for Climate Change," MacIntyre tweeted on Tuesday afternoon. "The opportunity to advance Canada's international #ClimateChange #CleanGrowth agenda was an immense privilege. I am confident Canada's important #climate leadership will continue."
Her husband, Michael Fink, passed away in October. He was 48 years old.
The couple met when they were each in St. Petersburg, Russia.
According to an obituary, he had worked for the National Nuclear Security Administration — contributing to American efforts to "secure weapons-grade nuclear material around the world" — and was dedicated to the cause of nuclear non-proliferation.
"Michael spent the final years of his career with Switzerland's Arktis Radiation Detectors, and his daughters are always proud to say 'Daddy works to stop bombs,'" the obituary said.
MacIntyre was appointed in June, filling a position that had been vacant since January 2015. She was previously Canada's ambassador to Switzerland and Liechtenstein.
