1.What does the "X" in the RNAV (GNSS) X RWY 09 approach mean?
There are two other RNAV approaches for RWY 09 and Nav Canada identifies them via the alphabetical suffix after the indicated nav aid used. Pilots should carefully confirm the approach identifier to make sure they will be flying the correct procedure.

2.This approach is indicated as LPV. What does LPV stand for?
Localizer Performance with Vertical Glidepath. It is basically the RNAV equivalent of an ILS. 

3.Do you expect 24-7 altimeter coverage at CYYJ?
Yes, note the ATIS and LWIS frequencies and the Remote Altimeter Setting Source box is empty, indicating that 24-7 coverage is available at the aerodrome.

4.To do the LPV approach, your GPS must be equipped with ______.
 WAAS, or Wide Area Augmentation System. Note the WAAS channel 80200. 

5.What is the minimum altitude permitted between DAXET and AGBAR, assuming you've been cleared for the approach, and how much obstacle clearance does it provide?
3,100 feet ASL and 1,000 feet of obstacle clearance. 

6.Am I correct is saying that the glidepath on this approach is 3.0 degrees?
Negative – note that it is indicated as 3.6 degrees.
