It seems he tried his VISA/PR or citizenship marrying a Candian woman.
Actually no, if you read the story, it says that he has been working in Canada for 10 years but married only for 2 and that they had a daughter. If he was already in Canada for 8 years before getting married, he could already have applied for immigration. Who knows why he didn't. Having a child with his wife doesn't point to it being a sham marriage either.
