I will second Blackadder's comment, coming from the Health Service Group.
You will be in the majority as a female in either of these MOSIDs. In the larger Royal Canadian Medical Service picture you will be a sizable minority at 25-30%. In the Royal Canadian Dental Service you will be in the majority / minority by 5% either direction no matter where you are posted. There two Services / Corps are not reflective of the rest of the CAF. For instance, both the Sr MLab Tech and Corps CWO for the Dental Corps are female right now and this is not a abnormal or a surprise to anyone.
As a male, who has employed both MOSIDs I have never given much thought to if the NCO / Warrant serving under my command was male or female. I just care, especially in the case of the MLab Tech, that they are highly self-motivated and competent. Not particularly interested in their gender, just quality of their work.
