"Being white in this country, I should just shoot myself. My kid is part not-white, so can we get somebody to see him that at least speaks English?"
The Sunday afternoon rant was captured on video by a man - an immigrant, according to HuffPost Canada - waiting to see a doctor at Rapid Access to Medical Specialists in Southern Ontario, near Toronto.
The footage has sparked outrage throughout Canada.
"I couldn't help but record the video," Hitesh Bhardwaj told the Canadian Broadcasting Corporation. "This is bad, this is inappropriate and shouldn't go unnoticed. I couldn't stop thinking about it. The whole episode kept on repeating in my head, I was very upset. You know I can't even define the feeling."
Kathleen Wynne, the premier of Ontario and the leader of the Ontario Liberal Party, called the video "disturbing" and said it raised questions about how far Canada had come in achieving racial harmony.
"I think we all should be shocked," she said. "If we're not shocked, that is a real problem. Sometimes we make assumptions about how far we have come about being an inclusive society and then when an incident like this happens, we have to step back and say what is going on?"
Nadia Alam, the president-elect of the Ontario Medical Association, said that the vitriol the woman expressed was extreme, but that her sentiment wasn't uncommon.
"I've seen it through medical school, I've seen it through residency, I've seen it on and off through my practice," Alam told the CBC. "Sometimes it is openly like, 'I'm not going to see you because you're this skin color or you have this accent. I want to see somebody else.'
"You think that you're a Canadian, that this is your country, this is where you belong. And when someone accuses you that way or treats you that way, you feel like an alien."
More than half of Mississauga's 700,000 residents are ethnic minorities, according to the Canadian Census, and more than 20 per cent hail from South Asia.
Police said they were called about a disturbance at the clinic on Sunday.
Constable Mark Fischer told CTV News that a woman at the clinic was "being verbally aggressive" in demanding a white doctor.
"The officer found that no criminal offence has been committed or was in the process of being committed," Fischer told CTV, so the case was closed.
Police said a doctor at Rapid Access to Medical Specialists eventually treated the boy.
A woman who answered the phone at the clinic on Wednesday said officials there had no comment.
But officials later said: "The clinic is proud of the quality of medical care provided at this clinic."
In the video, staff were polite to the ranting woman. But people in the waiting room couldn't take it.
They told her to go to another facility if she didn't like the colour of the doctors and defended doctors with accents.
And at one point, another woman got in the ranting mom's face and said: "Your child clearly has more issues with you being his mother than him needing to see a doctor. You are extremely rude and racist."
But the ranting woman turned her ire on Bhardwaj and the other people who confronted her.
"You're brown," she shouted. "You're brown. You're all attacking me because I'm white."
The woman in the video has not been publicly identified, though CTV News reported that "two women who were friends with her until a few months ago recognised who was in the video right away."
CTV noted that the woman from the video "didn't respond when asked for comment".
A sociology professor from Ryerson University in Toronto said "everyday racism" is "beginning to resurface" in Canada.
"I think people are feeling that there's a little bit more space now to question who's in positions of power, who's actually getting the jobs, those sorts of things," Cheryl Teelucksingh told CBC News.
She believed non-white professionals would start demonstrating their credentials by saying things like "I went to school this long and did this sort of specialty".
"They're legitimising not just their place in their profession and workplace but their place within Canada. To say, 'look, I actually belong here and I have the right to practice my profession'."
