Following the completion of the "Midget" level of Minor Lacrosse (ages 15 and 16), male and female players enter "Major Lacrosse". Major Lacrosse differs from Minor Lacrosse in many ways. For example, there are different rules with respect to body contact, different insurance considerations, and, increased travel to other cities in the Province.

In the Province of Alberta, Major Lacrosse is governed by the Rocky Mountain Lacrosse League (RMLL). Major Lacrosse consists of the Senior Division, for players over the age of 21 years who still want to play competitive lacrosse and the Junior Division for players between the ages of 17 and 21 years old.

There are four Junior Divisions within the RMLL: Junior "A" (4 teams), Junior "B" Tier I (8 teams from Alberta; 2 teams from Saskatchewan), Junior "B" Tier II (17 to 19 teams) and Junior "B" Tier III (13 to 15 teams) and a Junior Ladies Division (8 teams).

The Junior "A" and Junior "B" Tier I teams field their rosters through protecting players previously signed to their team and by using a "draft" whereby the teams in these Divisions are allowed to "draft" players from the pool of Graduating Midgets, Junior "B" Tier II, Junior "B" Tier III players and "free agents", which are eligible players who may not have played lacrosse for a season or two. The "draft" exists to ensure highly skilled players are provided the opportunity to play at the highest level of their ability and to promote parity amongst the Junior "A" and Junior "B" Tier I teams in the Province. This differs from Junior "B" Tier II and III, where players are assigned to teams via an "Evaluation Process" made up from a team's previously signed players, the Graduating Midgets from the Minor Club Affiliation and from "free agents".

In 2007, the number of players registered in Alberta in the four Junior Divisions and the Junior Ladies Division were:
Junior "A" - 94;
Junior "B" - Tier I - 183;
Junior "B" - Tier II - 346;
Junior "B" - Tier III - 258;  Note: Edmonton has no Tier III program.
Junior Women - 75.

                                         Excluding Junior "A", the average age composition of this division is:

								Age	%
								17	30
								18	25
								19	20
								20	15
								21	10

55% of the players in the Junior "B" Divisions are within the ages of 17 & 18. Thus this division is similar to moving up in a community-based lacrosse organization. The older players are still playing simply because they enjoy the game.

The Junior "B" Tier II and Tier III Divisions of the RMLL allow players to (a) continue in lacrosse and (b) develop their skills if they wish to evolve to the highly competitive Junior "A" and Junior "B" - Tier I Divisions.
All the Junior "B" levels require commitment, skill, and a desire to continue learning the game of box lacrosse.

The Okotoks Ice Junior Lacrosse Club has a Tier II team, the Okotoks Ice and a Tier III team, the Okotoks Icemen. For further information click on :    Okotoks Ice Junior Lacrosse Club
