Visitor Visa or Open Work Permit

[shosilie]

I joined my company on PG work permit and Im currently on (LMO based) work permit with the same company.

My family (wife and kids) are still in my home country, they are in the process of applying for TRV to come here,

Please, which one gives them better chance of being granted visas to come to Canada

1. Tourist Visa  for all of them

OR

2. Open Work Permit for wife and student visa for kids?

Thanks
