I can't relate to this at all. Sure, its annecdotal, but in Toronto, our restaurant diversity is second to none. My neighbourhoods grocers, in addition to the Canadian staple oligopolies, also has an abundance of smaller ethnic grocers within walking distance of my house. Chinese, Indian, African, Middle-Eastern etc.
As a white dude, I literally shop the world and cook the world using imported products and ingredients. Though I admit, we are lucky to be at the forefront of this globally.

We're spoiled here. Unlike say, the US where immigrant communities Americanize ethnic foods to cater to the local palate, our food scene is by expats, for expats and everyone else is welcome to join them. Dishes are as authentic as they can be right down to regional variations. E.g. Gudjarati Vegetarian, Hyderabad biryani, Chettinad cuisine, Cantonese, vs Taiwanese vs Hakka, Japanese or Korean and pretty much everywhere else.
I'll admit you have a point but only in that when travelling, "The West" is not a monolith., Most of Europe is quite a bit behind us in this regard; France, Germany and Poland, Portugal etc. They have such excellent local cuisines, authentic ethnic is limited to enclaves and has a slight homoginization with local traditions. A special shoutout to the UK who have reliably great Indian and Carribean cuisine even way outside of London. Then the US is generally a disaster as almost everything is Americanized and authenticity is murdered.
Its a broad generalization with exceptions of course, but as a Canadian, especially from Toronto, your characterizations sound silly from my perspective.
