In general, all of the above seems accurate and I agree. Just a few caveats. 1) While Montreal has one of the historically oldest gay scenes in North America, its progressive liberalization of attitudes towards LGBTQ+ was - as in many cities with thriving gay scenes - was greatly set back by the AIDS crisis in the 1990s. The Montreal police, like most police forces, have also had a long history of homophobia.
There's a great true crime podcast called The Village about the intersection of violence against LGBTQ+ communities and victims, and law enforcement (or lack thereof...). S3 of The Village focuses on the serial killer preying on gay Montreal men in the 1990s, and the fact that the Montreal police couldn't be bothered to actually investigate until gay activists got together to pressure the police and increase awareness in the community. Activism around AIDS and the Montreal serial killings of gay men helped solidify the Montreal gay community as it is today, from what I've read. (There was also a serial killer preying on gay men of immigrant backgrounds in Toronto - also covered in S1 of The Village CBC podcast - and the Toronto police basically ignored the reports of missing men and lackadaisically "investigated" to the point that they, at one point, had the serial killer in for questioning and they let him go.) So while Canada as a whole, Quebec and Montreal specifically, have made greater strides towards LGBTQ+ rights = human rights, they are not without their very recent problems. Like most big cities with thriving gay scenes, Montreal's LGBTQ+ community still suffers from homophobic law enforcement.
2) Religion is also a factor imo. Of those who consider themselves religious, the majority of Montreal is Christian, and the majority of those Christians are Catholic (per Wikipedia). Conservative observant religious (including Catholic) groups are typically homophobic. They also tend to whine that attempts to control hate speech stifle "free speech," as if it's perfectly fine to verbally abuse people. Very Christian of them, no? đ When the Montreal group Gai Ăcoute tried to create a registry of homophobic hate crimes - that included verbal assault with homophobic slurs/hate speech - in order to study the scope of homophobic hate crimes in Montreal, because they got financial support from the Quebec government, various Canadian religious groups protested this use of tax dollars. Which is probably why I could never find the results of that registry and the study they were going to do. It may have been shut down due to pressure or government budget cuts, which always disproportionately affect minority and marginalized groups first. (Or it may have been published in French, which I can't read. But the study results would've been covered in the English Montreal/Quebec press as well - and I never found the results in English, either.) Quebec/Montreal school initiatives to increase tolerance/decrease homophobia in schools have also been cut (for "budgetary reasons").
3) Lastly, Quebec, Montreal, and the rest of Canada are no less vulnerable to the rise of online social media-spread hate (manosphere, fascists, right wingers) and negative engagement-prioritizing algorithms (which all social media platforms use) than any other part of the world. Researchers found that homophobic sentiment more than doubled between 2017-2018 and 2023-2024 among Quebec high school students. (https://montreal.citynews.ca/2025/01/16/intolerance-2slgbtq-increasing-quebec-schools/) Considering how many traditionally liberal-social-values-espousing Western nations have struggled with rising divisiveness, hate, and fascism in the past 10-15 years - and within the time frame the GC books cover - it's really not surprising that Canada (and Quebec, and Montreal) would too.
4) Also factor in that players on sports teams aren't necessarily from the cities where their teams are - in fact most are not - and they may not have the same values that the city of their team espouses. They might be from countries, small towns, and/or rural areas where homophobia is alive and well and by which they were indoctrinated starting very young. Hockey as a sport is not particularly open-minded, even in Canada, if this report is anything to go by.
All of that having been said - it is highly sketchy that Reid wrote all the Quebecois players as homophobics who turn on Shane, and Hayden as Shane's sole supporter. I'm not sure if that's because of her writing, or because the romance genre in general has major inherent limitations (even m/m sports romance) due to publisher preferences (requirements, in many cases) for cliche-ridden, trope-dependent, formulaic content that generally relies on one-dimensional villains and easy, unrealistic solutions to get to the HEA (happily ever after). Maybe it's a combination of Reid's writing and the genre itself.
As you put it yourself, It's more like there was no further introspection done on the implications on what was written. Which is exactly my problem with the genre itself, including Reid's writing.
The major romance writers professional organization (Romance Writers of America) itself is super problematic. And most romance publishing houses have very strict requirements for things like word count, content, etc. It is not a genre I choose to read (I made an exception for the Game Changers books) because I find romance books predictable and boring due to their reliance on pretty strict genre conventions. (Romantasy books are similar, but at least there's fantasy tropes in those.) Reid's GC books did not change my attitude toward the inherent limitations of the genre itself at all. After I finish the upcoming last GC book I don't plan to read any other m/m romance novels - hockey/sports or otherwise. Frankly I have found far better, and much more satisfying, m/m reading in good fanfic. But maybe that's just me.
