The rules of the Royal Canadian Golf Association (Golf Canada) govern play.
Out of bounds:
Defined by white stakes and/or white lines and/or green fence and/or stone wall. Stakes, fences or walls defining out of bounds, are deemed to be integral parts of the course; therefore, there is no relief without penalty.
-On right of fairways : #1, #2, #3, #6, #7, #8, #9 and #18
-On left of fairways : #1, #3, #5, #11, #13 and #17
-Behind greens : #16 and #18.
A ball resting in an area which the player and his playing partners agree would normally be marked under rule 25-1, may receive relief.
Lateral water hazards:
Defined by red stakes and/or red lines:
#2, #3, #4, #5, #6, #7, #11, #13, #14, #15, #16, #17 and #18.
A ball embedded in its own pitch mark throughout the green, may be lifted, cleaned and dropped without penalty as near as possible to the spot where it lay but not closer to the hole.
Stake trees and their support, flower beds, rocks lining the teeing grounds and pathways are considered immovable obstructions. Relief with no penalty.
Appendix 1 (Definition): Establishing special areas on which balls may or must be dropped when it is not feasible or practicable to proceed exactly in conformity with Rule 26-1.
The Committee permit or require strongly the use of a dropping zone for the 4th, 15th and 16th hole. (16th: Black Tees only)
“If a ball is in or it is known or virtually certain that a ball that has not been found is in the lateral water hazard beside the 4th and 16th greens, the player may:
(i) proceed under Rule 26-1; or 34 Guidance on Running a Competition
(ii) as an additional option, drop a ball, under penalty of one stroke, in the dropping zone.
Stones in sand traps are considered as movable obstructions. They can be removed without penalty.
