if i get a trv on the reason yo meet my kids why would i be denied entry? What kind of law is this that separates a father from his kids.
It is you and your family that have separated by living in different countries. Stop trying to put the blame on someone else.
This whole situation is ENTIRELY the result of actions you and your spouse have taken. Your spouse's fault she did not declare you. Your collective fault you're no longer (apparently) in a relationship. Etc.
Not to mention the continual attempts to avoid the truth and omit critical information. Misrepresentation as far as the eye can see.
Get a lawyer, and stop bothering the kind-hearted people here who've been attempting to provide useful information.
You are in the hole you dug, and Canada doesn't owe you anything.
