I'm surprised it's that way in Canada but it's less to do with religion and more to do with culture is what I have observed.
People see religion nowadays as not a spiritual path or way of life but a culture ID like thing.
Religion in reality would permit such things and in Islam our Prophet(SAW) even married woman of different religion but whom converted mostly.
You see the problem is, I feel bad for you if you don't have other options for example to go to Pakistan and get married.
I have the option to go to Palestine and get married and also the option to get married here and if I get full of myself the option to date a girl and get married.
But I'm refraining from dating not because it's 'haram' it's actually haram because it most likely won't end up in a dedicated relationship and most people's intentions are to date numerous girls.
Had dating led to dedicated relationships Islam would have permitted it.
So I'm personally not really wanting a Muslim here unless I can find some Pakistani woman here I have a lot in my community and they have a balance between American and Muslim culture unlike some Arabic girls here.
However, i have many advantages to go to Palestine and get married but there is still a future ahead and who knows who I will know of later.
I'm sorry if it was a real thing and it's got to you, but, if you can't do anything about it don't sweat it. All guys are like you trust me, we used to have the view of getting one girl and everything is over if it's not the way we want.
It's bad for our energy and wastes our time because we all know how we see another girl later and think 'Oh, she's the one I feel it'.
Truth is there are literally thousands of girls of your taste in personality, beauty, manners, etcc... And you will be happy one day.
We all have been in your shoes so hope this makes you feel better.
Always have a good guy talk. Makes things better.
