Curling Canada guidelines covering recent technological advances in brush-heads are now in place for the remainder of the curling season.

A moratorium has been issued on the use of various brush-heads, and will be in place for all regional and provincial playdowns that lead to national and world championships.

A moratorium also is in place for the 2015 Canada Cup, which begins Wednesday in Grande Prairie, Alta.

The moratoriums, which have been agreed to by both the Grand Slam of Curling and the World Curling Players Association, fall in line with the World Curling Federation’s statement on brush-head technology earlier this month, which can be seen by clicking here.
