Tradução - I'm studying in Turkey (Inglês)

Merdogan,
gelmek could also be translated as arrive, so as lilian said before you can use "arriving in canada".
Lilian,
Maybe you should edit in this way.

Hello Lilian, the speaker is talking to anyone who lives in Canada. So he/she said "come".

But..merdogan, why do you write "come IN Canada" so consistently?

Merdogan,

"I'm coming in Canada" is definitely wrong.
The correct preposition should be: "to"
You can say:
1- I will go to Canada
2- I will be in Canada
3- I will come to Canada
4- I will arrive in Canada

I believe one of these will convey the meaning.
