Men's Addiction Service Hamilton (MASH)

What this program does...

The Men’s Addiction Service Hamilton (MASH) is a safe place that welcomes men who are struggling with substance use problems.

Men’s Addiction Service Hamilton was planned, developed and implemented using the Ministry of Health and Long Term Care (MOHLTC) endorsed Ontario Withdrawal Management Standards.  Our committed team of program staff has extensive expertise in evidence-informed practice for men with substance use problems (including tobacco). The program is exceeding the Provincial Withdrawal Management Standards and continues to be a trendsetter and innovator in the field.

Our program services include: 24 hour /7 day a week crisis telephone support, residential withdrawal management, psycho-educational relapse prevention and recovery programming and treatment/next steps / referral planning, a very effective day program for clients in transition, a community tobacco addiction program and access to psychiatric sessions and a primary care physician through a partnership with the Shelter Health Network.

How this program helps...

Our goals are:

  • To provide safety, dignity and support to men in crisis related to their substance use.
  • To provide compassionate, expert care, information, and treatment options that assist men to make informed decisions regarding their health and recovery from substance use.

The team at MASH begins by talking with each individual to understand his specific needs and his willingness to be admitted to the withdrawal management program.

Our dedicated team has specialty knowledge and skills related to men’s substance use, concurrent disorders (mental illness and substance use) and trauma.  We have expertise in working with men who are intoxicated, in withdrawal and in crisis related to their substance use.
