yeah i would but roommate understandably doesn't want a random
i did the online form and they granted the extension, which i assumed meant automatic admittance for the entire period, so i didn't bring any supplementary docs to the airport. they interrogated me there for i think about 2 hours and even spoke to my roommate before eventually letting me in.
i later came in through the downtown YTZ airport and brought documents but didn't have to show any once he saw my extension was valid. i got in in about 5 minutes there.
spending time in toronto is one of the worst decisions i've ever made. it's strictly worse than chicago in every way and offers nothing in the way of an interesting cultural experience.
(ignore the above line if considering subletting my place
)
