I thought it would be appropriate to update this thread with the latest news about the meteorite, seeing as the subject was brought up over on the breaking news forum in this thread.
Thousands of space rocks to yield clues about asteroid from November 20 impact

A University of Calgary-organized team recovered more than one hundred meteorites from the November 20 meteorite fall southwest of Lloydminster, Saskatchewan/Alberta, which is expected to set a new Canadian record for the largest recorded meteorite fall.
Using the abundance of meteorites on the pond where U of C grad student Ellen Milley found the first fragments on November 27, Hildebrand calculated that about 2,000 meteorites of more than 10 grams in size occur per square kilometer in the northern part of the strewn field, and probably more than 10,000 meteorites of this size are on the ground altogether. Many local residents and landowners also found meteorites, as well as persons from across the prairies and meteorite dealers who traveled to Saskatchewan to try their luck.
Typing of the meteorite has been completed with the collaboration of Dr. Alex Ruzicka and Dr. Melinda Hutson, a husband and wife team at the Cascadia Meteorite Laboratory at Portland State University, Portland, Oregon.
“The meteorite is at the low end of the H4 type and may be transitional with type 3. It will take some more work to sort out everything, but we have good prospects to learn a lot about the rock’s history,” Ruzicka said.
A lower number in the classification indicates that a meteorite experienced less heating on its parent asteroid, making it of more interest to researchers and potentially to collectors as well. Lower metamorphic grades are relatively unusual in meteorites of the H, or “high iron” type, such as the Buzzard Coulee rocks.

Like the other 9 (IIRC) asteroids who's orbits have been determined, this one originates in the Asteroid Belt, although precisely where has yet to be determined.
A few example orbits of the ones we know so far:
