Why isn't a read variable being found in my bash script? [duplicate]

I'm not sure why I keep getting a not found error for a variable read from the console. I'm trying to test if the variable read (var) is equal to "q" or not with the if-then-else statement.
I have tried making "q" a variable (as it is now) and leaving it as a string inside the control structure. Both yielded the same result.
q="q"
read var
echo "var = $var"
echo "q = $q"
if ["$var" == "$q"]
then
echo "if completed"
else
echo "else complete"
fi
If I type in "q" I want "if completed" to be output but I keep getting:
"/home/adamgeds/Projects/bash.sh: 13: /home/adamgeds/Projects/bash.sh: [q: not found
else complete"
(I should also mention that I believe the "q" in the error refers to $var and not $q... if that helps.)
