Hi there's not such thing as a non-essential option in your tourist visa application,Hi,
May I know what is the NON-Optional(Essential) reason for which you are planning to travel? I am in the similar situation, but I am not sure what non-optional reason a visitor visa holder can give to travel, apart from travelling to Canada with their Spouse?
i am just using this term to differentiate to what other are calling "extended family members visa" or "family reunification visa" those are still tourist visa or in some cases ETA but a family member inside Canada usually a PR holder ask IRCC for a written authorization for their family member to enter to Canada for an optional or discretionary purpose visit,
if you don't apply because you either don't have a family member inside Canada or because you actually would like to go to Canada for business and pleasure them you have to wait for travel restriction to be lifted
in that case you can either wait for travel restriction to be lifted or go ahead an apply as a right now for a regular tourist visa like we all in this thread did, some of us apply for hope or having our tourist visa approved early so we could go do some travel as soon as travel restriction are over and some of us apply before the pandemic began, it is up to you.
