The defining moment in which Laurent Brossoit realized he’s now a pro wasn’t when he pulled on a Calgary Flames sweater.

It wasn’t when he signed the contract.

As for stepping onto the ice of a NHL arena he did that for a few years while with the WHL’s Edmonton Oil Kings.

That moment for the netminder who is currently with the rest of the Flames prospects at the Young Stars Tournament in Penticton B.C. was when he slipped on his new mask.

“The cat-eye cage” Brossoit said of the wires that protect his face which differ from the pattern allowed in junior. “A lot of goalies once they put that cat-eye cage on — I know it may sound dumb — but it’s a sign you’re at the next step.”

Brossoit the Flames’ sixth-round pick 164th overall of the 2011 NHL draft joins an unproven but crowded crease of goalkeepers hoping to don the Flaming ‘C’ this season.

With Miikka Kiprusoff’s expected retirement announcement coming down the pipe any day now the Flames are expected to turn the page with former KHL standout Karri Ramo and Joey MacDonald in Calgary Swiss standout Reto Berra waiting in the wings in the minors and Brossoit and Joni Ortio battling for the second AHL post.

Brossoit the youngest of the bunch at 20 years old could actually return to the WHL as an over-ager — although that’s not likely. But the team is not willing yet to put in writing as to who will play where.

“They told me not to sell myself short — try to make the Flames” said Brossoit who backstopped the Flames prospects to a 5-2 win over the Edmonton Oilers hopefuls to start the tournament Thursday. “They said they have high expectations of me and I should have the same.”

Barring an injury among the goalies in the Flames system — or a surprising return by Kiprusoff — Brossoit’s most likely landing spot will be the ECHL’s Alaska Aces.

That’s assuming Ortio — who started the 2011-12 campaign with the AHL’s Abbotsford Heat but returned to Finland mid-season and was the No. 1 goalie for HIFK Helsinki last season — can do a much better job in North America this time around.
