illegal fishing nets in canada?

i need a list of illegal fishing nets in canada asap

Is it illegal to bring back a conch shell from the Bahamas?

I am currently on vacation in the Bahamas and my sisters and I found a huge collection of big, beautiful conch shells. Are we allowed to take them home (we live in Canada)? Does anyone know if there’s a law in place?
Thanks

My husband moved a canadian woman into our home while I was on vacation.Is this Illegal?

I decided to go and visit my daughter fotr a visit to decide if I wanted a separation and three days later he drove to Canada and picked up a woman he met online.I’ve heard this is illegal.Is it?
