Thailand beat Canada by 13 runs in their ICC Women's World T20 Qualifying Event Shield semi-final to make it to the final, where they will play Zimbabwe.
The match was extended into a second day after Thailand's innings of 92 for six in 18 overs was as far as the match advanced before heavy rain caused an abandonment.
Canada then reached 79 for eight in reply despite Monali Patel cracking a quickfire 20 at the top of the order.
Wickets from Thailand slowed their progress, Nattaya Boochatham taking two for 11 to finish as the pick of the bowlers.
As Thailand prepare to line up against Zimbabwe with a fifth-place finish as their target, Canada will meet Japan in a match-up to avoid finishing in last place.
Meanwhile, Pakistan play Sri Lanka in the final and the one remaining qualifying place for the ICC Women's World Twenty20 in Bangladesh in 2014 will go to either Ireland or Netherlands, who meet in the third/fourth place play-off.
