"I wasn't ever in Canada" isn't accepted.
Did you report/flag it as "My answer should be accepted"? I think they'll add it as an acceptable translation (it is in my opinion at least)
After 319 days of practice I find I am able to spell most of the words. Learning how to spell the sounds in a word is so helpful. It is almost automatic!
I have never been to Canada was not accepted, why whould that be wrong?
"Have' is not a past tense. This lesson is about learning past tenses of "was" or "was not."
I've never been to Canada is accepted, now at least.
I am in awe of your streak.
