hey you're not alone
I'm also very serious about attending a US school.. pretty busy lately taking care of my applications, and still not quite done yet..
I sent my transcript to LSDAS on the last week of August, and it took about 2 weeks for them to process it. I'm not sure which Canadian university you go to, but my UBC grades got converted based on letter grades only (A+ -> 4.33, A -> 4.00, etc.) I'm pretty sure they're not gonna use their 98-100 -> 4.33 scale, so no panic there.
btw, which school do you go to? it appears that the mean GPA of LS applicants from UBC is 2.99 and the mean LSAT is 155.. No grade inflation here
