I wonder if foreign leading companies are good.

I still have a say in this, because I am a world leader in resettlement and employer-sponsored projects. They have their own direct operating companies in Canada, which can quickly match employers. They have been doing this for more than 20 years. If it's not good, it won't last that long. It's better to guarantee an unsuccessful refund. If you accept my answer, I hope you can help me adopt it.
