Oh,fkl said:I don't think so. It most likely won't work.
There are two CBSA rules which make getting the wp at border valid.
a) Only people who do not require visa to enter Canada can obtain work permit at the border. This excludes people with nationalities who need a TRV to enter Canada.
b) If you are already admitted to Canada on a valid study or work permit AND you are returning by land ONLY from the US, you DO NOT REQUIRE A VISA to enter Canada.
When people meet b, and they flagpole / return from US, they do not need visa to enter Canada and hence they qualify for obtaining WP at the border based upon a.
Now i have heard of cases where people were already in Canada on a visitor TRV (6 month max, no medical coverage), then they went to border and got a WP, but i don't know if that was just them being lucky. There is no actual law stating this.
So for the original poster here who would be entering Canada first time on a visitor visa, i don't think it would work.
But your best bet is to enter Canada as a visitor and ask about WP too. If they say yes you might get it there. Else apply from inside Canada latter. I don't see much difference between applying from US vs applying online from inside Canada. Both should take the same time.
Instructions and documents needed would come up as you attempt filling online form.
I didn't knew that.
I am sorry for my post because of the wrong information.
