MDS Summary

The Minimum Distance Separation (MDS) Formulae is a land use planning tool that determines a recommended separation distance between a livestock barn or manure storage and another land use. The objective of MDS is to prevent land use conflicts and minimize nuisance complaints from odour. MDS does not account for other nuisances such as noise or dust. MDS is made up of two separate, but related formulae: MDS I and MDS II.

MDS I – provides the minimum distance separation between proposed new development and existing livestock facilities and/or permanent manure storages located in areas where the keeping of livestock is permitted.

MDS II – provides the minimum distance separation between proposed new, enlarged or remodelled livestock facilities and/or permanent manure storages and existing or approved development located in areas where the keeping of livestock is permitted.

MDS Software Overview

To assist municipalities, farmers, consultants and the general public, OMAFRA has developed a software program for distribution and use with the MDS Formulae to facilitate and assist with calculating MDS setbacks.

Specific features of the MDS software include:

    • Windows XP/Vista compatible.
    • user-friendly interface.
    • can be used to calculate MDS I and MDS II setbacks.
    • allows MDS calculations to be saved and shared with other users of the MDS software.
    • Distances can be displayed in either metric or imperial units

When using the MDS software, OMAFRA is not responsible for errors due to inaccurate or incorrect data or information; mistakes in calculation; errors arising out of modification of the software, or errors arising out of incorrect inputting of data. All data and calculations should be verified before acting on them.

To assist municipalities, farmers, consultants and the general public, OMAFRA will identify an official version of the MDS software for the purposes of calculating MDS.

Information on Versions of MDS Software

OMAFRA has produced three versions of the MDS software which can be used with the 2006 version of the MDS Formulae. Versions 1.0.0, 1.0.1 and 1.0.2 are all considered official versions of the MDS software, and will calculate setbacks that accurately reflect the 2006 version of the MDS formulae.

The most current version of the MDS software used by OMAFRA staff is version 1.0.2. This version addresses a number of issues related to compatibility with Vista operating systems, and includes minor graphical updates to the MDS software program and print-outs; compared to versions 1.0.0 and 1.0.1. However, for the purposes of calculating MDS, versions 1.0.0, 1.0.1 and 1.02 are all considered official versions of the MDS software by OMAFRA.

Getting a Copy of MDS Software

When you order Publication 707 – Minimum Distance Separation (MDS) Formulae you will also receive a copy of the latest version of the MDS software.

If you have previously purchased a copy of Publication 707, and received either version 1.0.0 or version 1.0.1 of the MDS software, you can download an upgrade (53.5 MB). Versions 1.0.0, 1.0.1 and 1.0.2 are all considered official versions of the MDS software by OMAFRA.

Upgrading MDS Software

Instructions below outline the process for downloading a file which will allow you to upgrade your MDS software to version 1.0.2. This upgrade only works for users already operating MDS software version 1.0.0 or 1.0.1.

If you have an older version of MDS software, intended to support the implementation of the 1995 version of the MDS Formulae, please see MDS Formulae – Publication 707 – Ordering Information to obtain a copy of the most recent version of the MDS Formulae.

To download MDS 1.0.2, click below and follow the instructions. The file you are downloading is an upgrade program that will undertake all the necessary changes to your older MDS program.

  1. When you click on the link below, depending on your Windows configuration you will be asked whether to Save the File or Run the File from the Current Location. Both options work equally well. It may be convenient to save the file to your Desktop and then delete it once the upgrade has been completed.
  2. Once the file is downloaded, double click the file or click "Open" and the online upgrade will engage InstallShield©, a program which assists in the installation of the new version. Follow the InstallShield instructions.
  3. When installing the new version of MDS, your old version of MDS is over-written.
  4. When upgrading, your ".MDS", data files will not be changed, modified, or deleted.

Installation Troubleshooting

If you are unsuccessful in downloading the upgrade, please consider the following:

  1. When downloading, if your internet security settings are set to a restrictive level you may not be able to download an executable (program) file. Downloading any file from the internet has risks. If you lower your security settings in order to download this file, you should reset them to their previous levels afterwards.

  2. The download file is very large (55 MB) because it contains the InstallShield© software and Adobe Acrobat Reader. On slow internet connections, the downloading process may be slow.

  3. If you do not have the appropriate version of MDS installed on your computer (MDS 1.0.0 or MDS 1.0.1) this download will not install the newest version of MDS.

  4. When the new version of MDS is installed on your computer, it will change the icon used for the MDS program and saved files. In some instances, the icon used to represent your MDS saved files may not immediately change to the new icon. Generally, this issue will resolve itself over time, as the cached memory on your computer is updated.
