Just in time for what The Weather Network is calling a “messy” wintry Sunday with bad driving conditions, GO Transit has launched the new $10 unlimited Sunday Funday pass.

Buying the $10 pass gives you unlimited travel anywhere on the GO network.

Children 12 and under currently always ride free. The new Sunday pass will be in effect until Feb. 9.

Here’s how you do it: go online and pick either an Adult, Student or Senior pass. Type in your where you are going and then choose the "multiple rides" option, and simply fill out all the requested info.

Anyone over 13 is eligible for the pass (remember,  children under the age of 12 ride for free).

An online pass will be emailed to you once you complete the process. Good thing is, you can use it on your smartphone.

Remember this: you have to activate the pass five minutes prior to boarding a GO train or bus.

The new pass will be available every Sunday from Dec. 1 to Feb. 9, 2020.
