Mr. Speaker, this is a serious issue. The shortage is of concern. Other alternatives are available. Over 50% of the uses of TC99 are for heart scans. Thallium can be used as an alternative in many of these cases. The next largest use of TC99 is for bone scanning. Again, there are other alternatives. Sodium fluoride can be used in these cases.
We have approved clinical trials and special access program requests. This provides Canadians with greater access to alternatives. For the last 18 months, my department has been working very closely with the provinces and territories.
