So again, if I understand well the calendar year is applied for the visa exempt , two (2), but not for the extensions.
Further more if I understand you well, the 157 days limit is applied for a trip: 2 by 60days for the exempt plus one 30 days extension plus one 7 days extensions = 157 days.
Now for the new rules on visa exempts and visa extensions: I arrived here on october 17 and got in with a 2 months visa exempt and got a 1 month extension.
I was counting to do a border run to get a second 2 months visa exempt and then get an other 1 month extension before going back to Canada.
I know I can get my second visa exempt but with the new rules is it true that for your second visa exempt done overland you don't get a visa extension anymore or at the best a 7 days extension?
