i have already landed im in canada now, but if there is an interveiw i will fly back to england then fly back again after. will i need a travel document so i can get back into canada? if so how do i get one
update what i was asking about was multi entry visa bu i have found out that they are for non visa exempt places only so i cant have one
You are in Canada now, but you are not 'landed' in Canada - 'landed in Canada' means you come here with your PR visa and officially enter Canada as a permanent resident.
After the interview, you should be able to enter Canada again exactly the same way you did before: as a temporary visitor or tourist. UK citizens don't need a visa to enter Canada for a short time, so you should be fine.
