I'm going to be traveling across Canada, anyway to download a list of stores?
I'm afraid there is currently no support for downloading or offline functionality.
You could download all shops in json format from our data dumps. This can be opened in a spreadsheet or using other tools.
Are you going by car? If so, that's a long way! There's a very handy app for car diagnostics, you can download it here - https://play.google.com/store/apps/details?id=com.motordata.obd Thus you'll know your car's condition and be able to understand the source of the problem if any problems with the engine or something else.
