"I'm fat. I'll always have fat on my body, and that will never change," she wrote.
"And I'm okay with that. I am okay with being fat. I'm okay with not hiding behind euphemisms like curvy or shapely. I refuse to let a three-letter word define the course of my life, or how loud my voice is."
She wrote that she'd been excited to work for Reitmans, parent company of Addition Elle, which caters to women like herself. But the firing left her questioning their values.
"If a company like Reitmans Inc. will fire someone for using the word 'fat' to describe my place in their company, what does that say about the company?" she wrote.
"For me, it tells me that, despite the leaps and bounds of the body positivity movement, internalized hate and stigma against fat bodies still runs rampant."
