What is the ruling of the Sharia on a married young man with two daughters emigrating to Canada to improve his living conditions, then moving from there to an Arab country or returning to his home country?

In summary, it is not permissible to emigrate to lands of disbelief merely to improve one's livelihood, unless the means of obtaining the necessities of life in Muslim countries become difficult to acquire, or one fears for one's self, one's religion, and one's family, a danger that can be averted by emigrating to a land of disbelief, when there is no Muslim country that can accommodate one's living. The Sacred Law has forbidden residing in the lands of disbelievers because a Muslim there cannot openly practice the rituals of his religion except with difficulty. Furthermore, these are lands where trials and forbidden things are thought to be prevalent, and one cannot feel safe for oneself there.
