chances of canada tour anytime soon?

pretty new to the band and i was wondering about tour. i see that there is a US tour in september, is there a likely chance that they will be adding more US tour dates + some canada dates?

in the past did they announce tour dates in waves instead of all at once, and were there more dates than there currently are?

i reallyy want to see them and especially since everything is sold out, id love to get some canada dates where i can try for tickets :(
