No. The plural is "cancellations." Apostrophes show possession, not plural.
---
Perhaps because young students learn plurals, possessives, and contractions around the same time, the apostrophe is widely misused to form plurals. The only time apostrophes are correctly used in this way is when a word would be misunderstood using the S alone (e.g. "We counted the number of the's in the paragraph" meaning the word the). But italics are often used for that purpose. Where there are single letters, use uppercase, such as As and Os.
No. A spider is a spider and an apostrophe is an apostrophe.

This is an apostrophe.( ' )

Shall not with an apostrophe is shan't.
An apostrophe is not required.

The word "its" does not require an apostrophe when indicating possession, as in "The dog chased its tail." However, "it's" with an apostrophe is a contraction for "it is" or "it has," as in "It's going to rain today." To determine whether to use the apostrophe, consider whether you mean possession (no apostrophe) or a contraction (with apostrophe).
