SV is one kind of TRV, of course there is expiry, it will not go beyond the expiry of the passport, the parent can not renew SV, if they are in Canada, they can apply for EXTENSION of stay, if denied, then go back to your home country and apply SV again!you mean SV can expire? Damn. Why? It costs the govt nothing. Parents cannot work. Parents pay for healthcare themselves. So why can't they just let the parents stay long term till they pass on?
Rob, can you explain why SV has expiry date and needs to be renewed?
