VISA/PASSPORT

When Will the VISA/PASSPORT thing go into place when crossing the bborder between the US and CANADA?

I heard the border will not be as free to cross as it useed to be.
I am planning a trip up this summer and want to know if i will need a passport/visa or not this year.
Thanks

i believe it was Jan 1st. You need it to get back to the USA. Go to get it ASAP it is expense but if you have to Rush it later it will cost you even more.
